Hi @niqo01 ,

Thanks for reporting this! I haven't seen this error before, by reading the source code, it was logged here.

Could you provide a more detailed stacktrace if possible?
Is this happening on all users or a particular subset of users?

Thanks!

Hi @liuyang1520

I am not able to provide a more detailed stacktrace. It's happening on a small subset of production devices in the wild. If a new version the Amplitude SDK could return the actual exception in the logger, that would be great.

Hi @niqo01 ,

Got it. Is it possible for you to try this troubleshooting plugin? By reading the short error message above, it might be helpful to understand the event payload and see whether it is convertible to JSON.

Thanks!

Here is a stacktrace:

My guess is that the amplitude backend returns HTML response sometimes, probably for some 5XX or 4XX issues and when the SDK create a JSONObject for the response, it raises an exception.
