Getting the same error. Any solution?

Started seeing this also. Seems to be a recent breaking change in the OpenAI API.

The documentation doesn't say much about valid values for finish_reason, so I suggest we should treat it as potentially null.

I can do a PR maybe later today, will check in here in a few hours.

If anyone else wants to apply this fix without waiting for the new release (and you're using composer), change the package in your composer file like this and run composer update

"openai-php/client": "dev-main as 0.3.1",

Note that we are aliasing it as 0.3.1 so it will still work with other packages that use it as a dependency (e.g. openai-php/laravel)

(remember to change it back when a proper version is released!)

Fixed on v0.3.2.
