I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

This error is currently seen from the firebase console, which affects thousands of our users. I don’t have the code to reproduce it, but I think this should be a problem with the SDK itself, and I hope it can be resolved.

This library is collected by firebase itself. We have not actively called it, so I can't give you the reproduced code, but from the error report, it is obvious what the problem is. I hope you can solve it as soon as possible.

By the way, @hebehan. While we wait for our engineers to take a look into this. I noticed that you're using an older version of the SDK. Have you tried version 20.3.1? we usually advise this to avoid us looking for issues that might've been resolved in the most recent versions. Let me know if this works. Thanks!

We will consider upgrading the sdk version in the future, but please also ask your engineers to confirm whether there is a fix in the new version, if not, please fix it as soon as possible, thank you
