code works fine when ran independently on vscode, but I get this error when I deploy and send request from client side

I need an assistance, cause I'm sure am getting something wrong without knowing yet.

cloud function response error

sleek flicker Jul 4, 2023, 5:03 PM

#

This usually happened when the payload data is not a valid JSON.
Can you print the payload data and make sure it's a valid JSON with all the double quotes, trailing comma, etc.

idle turtle Jul 4, 2023, 5:07 PM

on the cloud function or Flutter code?

besides I appreciate you for reaching out @sleek flicker
can't take that for granted

sleek flicker Jul 4, 2023, 5:08 PM

#

In your cloud function code.

#

Actually where's the error coming from?
The App?
Can you share the code of how you're running the function?

idle turtle Jul 4, 2023, 5:09 PM

#

sleek flicker In your cloud function code.

How do I make it valid then?

#

{numberToProcess: 62626262666 , userMail: @mail.com , userID: 649f4aa7ab7ysy4b89ba0bd , totalServiceCharge: 200 , serciceTypeAndService: 9MOBILE CG , serviceQuantity: 500MB , walletBalanceDocumentID: 12222222222, networkID: 3 , planID: 329 , serviceName: Mobile Data, customerAmount: 200 , distributorName: none, meterTypeWithID: none, cableNameWithID: none, cablePlanWithID: none}

what was printed on Flutter before sending

sleek flicker Jul 4, 2023, 5:10 PM

#

What is your createExecution looks like?

idle turtle Jul 4, 2023, 5:13 PM

#

        functionId: 'automate_service_sender', data: jsonEncode(sendData));

    exec.then((response) {
      final decoded = jsonDecode(response.response);

      if (kDebugMode) {
        print("is: ${decoded.toString()}");
      }
    });

sleek flicker Jul 4, 2023, 5:14 PM

#

Okay this part looks just fine.

#

Can you share how you parse the payload in the server?

idle turtle Jul 4, 2023, 5:18 PM

#

dataFromClient = jsonDecode(req.payload);

#

And dataFromClient was declared as dynamic

sleek flicker Jul 4, 2023, 5:18 PM

#

Okay, and what do you see when you're printing the payload

print(req.payload);

idle turtle Jul 4, 2023, 5:19 PM

#

If I try to print that dart will say it does not understand the Appwrite variables and all of that

#

So I do comment them usually

sleek flicker Jul 4, 2023, 5:19 PM

#

upright?

#

Meaning?

idle turtle Jul 4, 2023, 5:20 PM

#

When debugging from vscode

idle turtle Jul 4, 2023, 5:22 PM

#

sleek flicker `upright`?

Appwrite I meant
@sleek flicker

It was a voice to text, was walking on the road

sleek flicker Jul 4, 2023, 5:32 PM

#

idle turtle So I do comment them usually

Comment what?
req.payload should be string
Can you print it, or you getting error trying to do so?

idle turtle Jul 4, 2023, 5:36 PM

#

Beginning from initialization of appwrite gives an error and when I change function name to main instead of start

sleek flicker Jul 4, 2023, 5:37 PM

#

You can't change the name

#

Make sure the function file structure it's like in the starter
https://github.com/appwrite/functions-starter/blob/main/dart-2.17/lib/main.dart

idle turtle Jul 4, 2023, 5:41 PM

#

Okay

#

    client
        .setEndpoint(req.variables['APPWRITE_FUNCTION_ENDPOINT'])
        .setProject(req.variables['APPWRITE_FUNCTION_PROJECT_ID'])
        .setKey(req.variables['APPWRITE_FUNCTION_API_KEY'])
        .setSelfSigned(status: true);
  }```

Isn't the above where initialization starts?

sleek flicker Jul 4, 2023, 5:47 PM

#

Yes

idle turtle Jul 4, 2023, 5:48 PM

#

Okay

#

Maybe I'll call start from main

sleek flicker Jul 4, 2023, 5:49 PM

#

I think you should remove the main function from your code.

idle turtle Jul 4, 2023, 5:49 PM

#

Though before deploying the function I always used start but if am debugging I always replace start with main

sleek flicker Jul 4, 2023, 5:49 PM

#

sleek flicker I think you should remove the `main` function from your code.

Let it all run inside the start method

sleek flicker Jul 4, 2023, 5:49 PM

#

idle turtle Though before deploying the function I always used start but if am debugging I a...

Gotcha, makes sense.

idle turtle Jul 4, 2023, 5:50 PM

#

sleek flicker I think you should remove the `main` function from your code.

But how do I test it while debugging because dart will always say it does not recognise the presence of main function in the code

idle turtle Jul 4, 2023, 5:50 PM

#

sleek flicker Gotcha, makes sense.

?

sleek flicker Jul 4, 2023, 5:52 PM

#

For that
You can first upvote this issue: https://github.com/appwrite/appwrite/issues/5425

Second you can create another file in your project for now, name it local-server.dart I'll write the code in a minute.

idle turtle Jul 4, 2023, 5:52 PM

#

Okay

sleek flicker Jul 4, 2023, 6:01 PM

#

local-server.dart

import './lib/main.dart' as user_code;

void main() async {
  await user_code.start(Request(), Response());
}

class Request {
  final Map<String, dynamic> variables;
  final Map<String, dynamic> headers;
  final String payload;

  Request({
    this.variables = const {},
    this.headers = const {},
    this.payload = '',
  });
}

class Response {
  int _status = 200;
  dynamic _text;

  int get status => _status;
  dynamic get body => _text;

  Response send(String? text, {int status = 200}) {
    print(text);

    return this;
  }

  Response json(Map<String, dynamic> json, {int status = 200}) {
    print(json);

    return this;
  }
}

#

Now you can keep your main file intact and just run the local-server

dart local-server.dart

#

Put the local-server.dart file in the main function directory.

#

Btw, you can add in the payload property inside the Request class any possible payload information, like:

  Request({
    this.variables = const {},
    this.headers = const {},
    this.payload = '{"username":"john", "age":22}',
  });

Okay

sleek flicker Sweet Put it inside your function like so ```dart client .setEndpoint("...

Try this

sleek flicker Try this

#

Worked

#

Wooooooooooooooooooow

#

#

a genius man
@sleek flicker

#

got response for first time in one week 🙁

#

This error ate my time but I will catch up

#

But why was other cloud function working with different address

#

.setKey(req.variables['automate_service_sender'])

idle turtle Jul 6, 2023, 5:11 PM

#

idle turtle ``` .setKey(req.variables['automate_service_sender'])```

this probably was the cause

#

no variable like that exist in cloud function, or what do you think was the issue, so I don't face that next time

#

The problem now was that Appwrite isolated function can't and won't be able to parse localhost as server localhost.

For this instance make sure you have - or you can create - a variable named automate_service_sender in the cloud

I didn't get you clearly @sleek flicker

#

thanks for standing by me, I'm super grateful

this bug was looking like something else

sleek flicker Jul 6, 2023, 5:16 PM

#

For you to able to get variables from req.variables map
You'll need to add it in your Appwrite console.
You can do so when you go to your function -> settings -> varaibles section

You can see in the example I've added the automate_service_sender now it will be accessible through the req.variables['automate_service_sender'] inside the function.

sleek flicker For you to able to get variables from `req.variables` map You'll need to add it ...

Okay, this was the cause of the error right?

sleek flicker Jul 6, 2023, 5:28 PM

#

Probably as you didn't had that value

idle turtle Jul 6, 2023, 6:26 PM

#

sleek flicker Probably as you didn't had that value

you're right

#

I appreciate you man, I didn't even think the error was from there

seems I may always chage the ip when my system restart right?

#

currently used

172.19.0.1 and it worked

sleek flicker Jul 6, 2023, 10:29 PM

#

Yes it just local address
