"401 Incorrect API key provided" even if it has the correct OPENAI_KEY (even after a API key update)

[EdoardoMolinatti]

Hi all,
first of all, I'm sure my OpenAI API Key works because I'm using it on a WSL2 machine (Ubuntu 22.04) on the same Windows 11 machine.

On a Windows 11 command prompt window (cmd.exe) I executed micro-agent (after installing it through npm).
The output was the following:

C:\Users\edoardo.molinatti>micro-agent
(node:25320) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.
(Use node --trace-deprecation ... to show where the warning was created)

micro-agent v0.1.4

Please open a Bug report with the information above:
https://github.com/BuilderIO/micro-agent/issues/new

As you can see I specified my OpenAI API key as requested, but it didn't work.
If I run micro-agent config I see that the key is correct, but I tried to update it re-pasting it after a double-check (using the command micro-agent config set OPENAI_KEY=<token>).
It still doesn't work (with the same error output).

Can you please tell me what could be wrong and/or what to check?

Thank you very much for any help
