My Edge Function fails or returns an error

Not checked against the vendor's current screens

What you may see

Calling my function gives 401, 500 or a timeout
It works when I test it myself

Most likely cause

The call lacks the login header the function requires, a secret the function needs was not set, or the code throws.

Check first (about two minutes)

Open the function's logs in the dashboard at the time of the call.

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a careful senior engineer who knows Supabase (database, login and file storage) and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

THE PROBLEM
My Edge Function fails or returns an error

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
The call lacks the login header the function requires, a secret the function needs was not set, or the code throws.

DO THESE STEPS, IN THIS ORDER
1. Read the function logs I paste (no secrets) and the way the function is called.
2. Check whether the function requires a signed-in user and whether the call sends the header.
3. Check the secrets the function reads exist in the function secrets settings (names only).
4. Add CORS handling if a browser calls it, and catch errors with a clear message.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A test call returns 200 and the logs show no error.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not turn off login checks on the function.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Read the function logs I paste (no secrets) and the way the function is called.
Check whether the function requires a signed-in user and whether the call sends the header.
Check the secrets the function reads exist in the function secrets settings (names only).
Add CORS handling if a browser calls it, and catch errors with a clear message.

Do not do this

Do not print secrets in function logs.
Do not turn off login checks on the function.
