What exactly was the trace?

Did you see the execution start in the Appwrite console?

Summary

Summary: The user is discussing an error they encountered with a Functions SDK. They mention that they need to receive a certain header in order to confirm a message's origin. They also mention that when an error occurs, they only see a generic "Internal Server Error" message in the Appwrite function's dashboard. They are looking for a solution to these issues. Solution: It is recommended to catch exceptions and include more detailed error messages in the response. Additionally, the user should ensure they properly initialize and deploy their function. They can also create a function to reproduce the issue for further investigation.

sorry, I have deleted the function and rewrote it using the Deno SDK.
But what does happen on every script I write is, if it throws and error, I will see only an "Internal Server Error" message in the Error tab of the appwrite function's dashboard.

for the error I was having the error message was empty. The only information I had was that it happened in the function that tries to make a request to execute the function I requested in the appwrite's api.

it didn't work with the Deno's SDK either though, I had to do a workaround that would cost me more one request xD

TypeScript

/*
  'req' variable has:
    'headers' - object with request headers
    'payload' - request body data as a string
    'variables' - object with function variables

  'res' variable has:
    'send(text, status)' - function to return text response. Status code defaults to 200
    'json(obj, status)' - function to return JSON response. Status code defaults to 200

  If an error is thrown, a response with code 500 will be returned.
*/
export default async function (request: any, response: any) {
    throw new Error(
        'Environment variables are not set. Function cannot use Appwrite SDK.',
    )
}

if I don't catch the error and send it in the response, I'll have no idea of what went wrong xD

For now, it's best to always make sure you catch exceptions and return a response

one important thing I gotta ask you though is: do you know why the headers variable may be empty?

I created a function to receive updates from Stripe webhook but I need the stripe-signature header to confirm the message belongs to Stripe

yeah, I just saw yours after creating mine XD https://github.com/ssa-web-solutions/appwrite-functions-proxy
Not as professional as yours but works (it's lacking an auth layer though)
