[SOLVED] Error in function execution

Iam new to functions and i want to execute a function that triggers when the payment is made on adapty .
The function should update the a attribute in user database and also there should be another function that changes the attribute again after a specific time period
I have copied and changed the code from the internet , is the code correct
The errror that shows in appwrite is:
TypeError: userFunction is not a function
at /usr/local/src/server.js:68:19
at processTicksAndRejections (node:internal/process/task_queues:96:5)

And also is there any way to test the functions locally using postman

When using Appwrite function - in current versions - it's vital to keep the Appwrite main exported function.
In your case its seems like you're using the Appwrite node function.
For that the only exported function should be something like this

const sdk = require("node-appwrite");

module.exports = async function (req, res) {
    const client = new sdk.Client();

    const database = new sdk.Databases(client);
    // Other modules

    // Function code.

    res.json({'success': true});
};

As Appwrite will always try to load on function with this signature

You can use Appwrite CLI To generate your functions:

https://appwrite.io/docs/command-line

appwrite init function will create your function with all necessary files then use appwrite deploy function to upload the changes to appwrite (make sure to select the function pressing the space bar)

To execute a function from postman you should send a POST request to /v1/functions/{functionId}/executions with the functionId param

Make sure your function have the right permission to be executed

I changed the code to this, but now it is showing error as:

An internal curl error has occurred within the executor! Error Msg: Operation timed out

@Binyamin What should i put in the place of endpoint

Are you using appwrite cloud?

Yes??

sorry iam not using appwrite cloud , iam using the normal functions in appwrite

Have you set the project and api and this is just an example?

Thank you for helping out, i resolved the issues

Can we trigger the function when a payment is made on adapty?

To be able to that
You'll need to have a webhook towards your function.
In the next Appwrite function release it will be an option, for now you'll need to use something like this
https://github.com/Meldiron/railway-webhook-proxy

So even if i set webhook endpoint to the appwrite function , it wont be executed. I have to set the webook proxy using railway?

For now, yes.

Because as of now Appwrite function require you to send project ID and this part can't be done with URL variables.

Check this - in the Future possibilities section.
