Description

We have our own API server and auth service for Azure OpenAI, the apikey used in the config is actually a JWT (with 2 dots in it to split the header, payload and signature), not sure if something added from 0.8.63 that parses the apiKey and breaks json body.

0.8.63 and the latest prerelease 0.9.245 both have this error, haven't tried any other prerelease versions but suppose to be the same error.

Rollback to 0.8.61 and any versions before are ok without any error.

To reproduce

No response

The \"lazy\" comment must always be a valid comment in the current context (e.g. \"<!-- ... existing code ... -->\" for HTML, \"// ... existing code ...\" for JavaScript, \"{/* ... existing code */}\" for TSX, etc.)\n6. You must always provide 1-2 lines of context above and below a \"lazy\" comment\n7. If the user submits a code block that contains a filename in the language specifier, always include the filename in any code block you generate based on that file.
