Upon each start for the last 2 hours on my project I keep getting Convex failed to start errors and when asking Chef to fix he is unable cause all Type Script check functions fail and a lot of times we fail to push to convex, please need help as I have lost time, money, and the ability to preview my project completely.

Hi @fickle olive. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

I understand you're experiencing issues with TypeScript errors preventing your Convex functions from starting properly. Based on the information provided, this appears to be a common issue when working with Convex and TypeScript.

Possible Solutions

  1. TypeScript Errors Blocking Deployment:
    By default, Convex blocks deployment when there are TypeScript errors. You can bypass this with a flag if needed while you fix the underlying issues:

    npx convex dev --typescript-skip

    This allows you to deploy despite TypeScript errors, which might be useful as a temporary solution Discord support thread.

  2. Copy-Paste TypeScript Errors to Fix Them:
    A recommended approach is to keep TypeScript running in a terminal window throughout development to monitor your code's health. When you encounter errors, you can copy them and work through fixing each one systematically Stack.

  3. Check for Import Issues:
    Many TypeScript errors in Convex are related to import problems:

    • Ensure you're not importing React Native dependencies in your Convex files
    • Check for path alias issues in your imports
    • Make sure you're using the correct file extensions (.jsx for JSX syntax)

  4. TSConfig Issues:
    There might be conflicts between your project's tsconfig and Convex's tsconfig. Make sure your root tsconfig properly excludes the Convex directory or is configured correctly to work with it.

#
  1. Check for Random API Generation Errors:
    If you're using ts-api-spec or similar tools, there have been issues with these failing randomly. Updating to the latest version of convex-helpers (0.1.64 or newer) might help resolve these issues Discord support thread.

If you continue to experience issues, providing specific error messages would help in diagnosing the exact problem. The TypeScript errors are preventing your functions from being pushed to Convex, which is why your project isn't starting properly.

I can see the specific error you're encountering now. This is a validation error from Convex, which is a common issue when working with validators in Convex functions.

The Problem

The error message indicates:

ArgumentValidationError: Value does not match validator. 
Path: .status 
Value: "in_progress" 
Validator: v.union(v.literal("pending"), v.literal("completed"), v.literal("needs_return"))

This means you're trying to use a status value of "in_progress" in your query, but your validator only accepts "pending", "completed", or "needs_return" as valid values. This is a mismatch between the data you're passing and what your function's validator expects.

How to Fix It

  1. Update your validator to include "in_progress" as a valid status:
// In your Convex function file
export const listServiceCallsByStatus = query({
  args: {
    status: v.union(
      v.literal("pending"), 
      v.literal("completed"), 
      v.literal("needs_return"),
      v.literal("in_progress") // Add this line
    )
  },
  handler: async (ctx, args) => {
    // Your function logic
  }
});
  1. Alternatively, change the status value you're passing to match one of the accepted values ("pending", "completed", or "needs_return").

Why This Happens

Convex uses validators to ensure type safety at runtime Functions > Argument and Return Value Validation. This is a security feature that prevents unexpected data from being processed by your functions. When the client sends a value that doesn't match the validator, Convex rejects it with this error.

#

This is a common issue when:

  • You've updated your frontend code to use new status values but haven't updated your backend validators
  • You have different status values in development vs. production
  • You're using values from an external source that don't match your validators

Best Practices

  1. Keep validators in sync with your schema to avoid duplication and inconsistencies Stack > Types and Validators in TypeScript: A Convex Cookbook

  2. Use exported validators across your codebase to maintain consistency:

// In schema.ts or a validators.ts file
export const statusValidator = v.union(
  v.literal("pending"),
  v.literal("completed"),
  v.literal("needs_return"),
  v.literal("in_progress")
);

// Then in your function
import { statusValidator } from "./schema"; // or "./validators"

export const listServiceCallsByStatus = query({
  args: {
    status: statusValidator
  },
  // ...
});

Once you fix this validator issue, your function should work properly and the preview error should be resolved.

It looks like you're still encountering the same validator error in your Convex function. Let me provide some additional guidance on how to implement the fix I suggested.

Implementation Steps

  1. Locate the function file that contains your listServiceCallsByStatus query function. This is likely in your convex directory.

  2. Update the validator as shown in the code example to include "in_progress" as a valid status.

  3. Push your changes to Convex using:

    npx convex push

If you're having trouble implementing this fix, here are some additional troubleshooting steps:

Troubleshooting

  1. Check for circular dependencies: Sometimes validator errors can occur due to circular imports between files. Make sure your validator definitions don't create import cycles Discord support thread.

  2. Verify validator syntax: Ensure you're using the correct validator syntax. The error suggests you're using v.union() with literals, which is correct, but double-check that you're importing v properly:

    import { v } from "convex/values";

  3. Consider using Zod: If you're having persistent issues with validators, you might want to try using Zod for validation through the convex-helpers package Stack > Zod with TypeScript for Server-side Validation.

  4. Check for multiple versions: Sometimes these errors occur if you have multiple versions of Convex in your project. Try updating all Convex-related packages to the latest version.

#
  1. Validate IDs properly: If your function uses IDs, make sure you're validating them correctly. For URL parameters, you might need to cast them as shown in this example:
    id: Route.useParams().campaignId as Id<"campaigns">
    Discord support thread.

Remember that argument validation is a best practice in Convex to ensure type safety and security Understanding > Best Practices.

I can see you're still encountering the same validator error with your Convex function. This error is occurring because you're trying to use a status value of "in_progress" that isn't included in your validator definition.

The Error Explained

The error message shows:

  • You're calling the listServiceCallsByStatus query function in the serviceHistory module
  • You're passing a status value of "in_progress"
  • Your validator only accepts "pending", "completed", or "needs_return"

How to Fix It

You need to update your validator in the function definition to include "in_progress" as a valid status value:

// In your convex/serviceHistory.ts file
export const listServiceCallsByStatus = query({
  args: {
    status: v.union(
      v.literal("pending"), 
      v.literal("completed"), 
      v.literal("needs_return"),
      v.literal("in_progress") // Add this line
    )
  },
  handler: async (ctx, args) => {
    // Your function logic
  }
});

After making this change, you'll need to push your changes to Convex with npx convex push.

Alternative Solutions

  1. Use a more flexible validator if you need to support dynamic status values:

    status: v.string()

    Then validate the specific values inside your handler function. However, this is less secure than using a union of literals Functions > Argument and Return Value Validation.

  2. Skip validation temporarily to get your app running while you fix the issue:

    npx convex dev --typescript-skip
#
  1. Use TanStack Query's skip option if you're using react-query with Convex:
    const { data } = useQuery({
  ...convexQuery(api.serviceHistory.listServiceCallsByStatus, {
    status: status as any, // Temporary workaround
  }),
  skip: status === "in_progress", // Skip this query when status is "in_progress"
});

Remember that keeping your validators in sync with your actual data is a best practice in Convex to ensure type safety and security Understanding > Best Practices.
