Hi @stx, I'm unable to reproduce this issue. Could you provide a complete minimal code that reproduces this?

[stx]

There is no Flutter code to reproduce the Google-side error.

These are production issues coming in from a large app so we're not sure what the triggering error is on the Google account.

Hello, without reproducible code, we are not going to be able to help you. Check the demo code to see if you can find the issue in your code:

@Lyokone how can a mishandled type in an internal exception in a plugin be an "issue with my code"?

[Lyokone]

The fact that we cannot reproduce it makes me think you might be misusing the plugin. I would love to improve our error handling, but the first step is for you to provide a reproducible sample.
Are you unable to provide code to reproduce the issue?

[stx]

The code to reproduce the issue is in the original post.

@stx A reproducible sample is a complete GitHub repo I can just clone and start on my end. A one-liner isn't a complete reproducible sample.
