Uncaught Error: undefined is not a valid Convex value (present at path [0] in original object

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

The error message you're seeing is due to the fact that undefined is not a valid Convex value. In Convex, you should use null instead of undefined. This is mentioned in the Convex documentation on supported types of values here (https://docs.convex.dev/functions/args-validation#convex-values).

The error message indicates that undefined is present at path [0] in the original object. This suggests that the first element in the object/array you're trying to use is undefined.

You might want to check your code to ensure that all values are defined and are valid Convex values before using them. If a value could be undefined, you might want to provide a default value or handle this case explicitly.

For example, if you're using a function that might return undefined, you could do something like this:

const value = someFunctionThatMightReturnUndefined();
if (value === undefined) {
  // handle the case where the value is undefined
} else {
  // use the value
}

If you're dealing with an array, you might want to filter out undefined values before using the array:

const array = getArrayThatMightContainUndefined();
const filteredArray = array.filter(item => item !== undefined);
// use filteredArray

Remember, Convex supports the following types of values: Id, Null, Int64, Float64, Boolean, and String. Make sure to use these types of values when working with Convex.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@young niche do you see how you could get undefined?
