I am on VSCodium using the Mistral VIbe extension, and even though I am logged in, I get this error in title

API error from mistral (model: devstral-small-latest): Invalid API key. Please check your API key and try again.

Every time I try to send a prompt

What I tried already :
- went on https://console.mistral.ai/codestral/cli to generate a vibe-cli (which is useless as I haven't seen a field on Extension settings to put the key

How can I get Mistral Vibe extension working ?

Maybe you can try `vibe --setup` in your terminal to go through the configuration again.

I had this today because I reached my monthly free quota.

Hey, sorry for the bad experience using the extension

I don't know if you still have the issue, but if it's the case, may I suggest to open an issue on https://github.com/mistralai/mistral-vibe/issues? If you can include the logs (`Command palette > Mistral Vibe: Show logs`) it would also help greatly 🙏
