I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

[rizafran]

Hi @mehulios, could you provide the detailed steps you made to reproduce the issue?

[paulb777]

Based on the backtrace, there may be an interoperability issue between Firebase Performance and Ultra SDK

[mehulios]

Hi @mehulios, could you provide the detailed steps you made to reproduce the issue?

This is the only details we have from firebase Crashlytics. This has happened to some random user.

[mehulios]

Based on the backtrace, there may be an interoperability issue between Firebase Performance and Ultra SDK

@paulb777 Can you please elaborate more on this.

[paulb777]

Firebase Performance and Ultra SDK may may do swizzling in an incompatible way. Given that the crash is actually closer to the Ultra SDK, it might be better to start the investigation there.

[mehulios]

@paulb777
The user has never utilised any Ultra SDK-related journeys prior to this crash. Please locate the precise logs that list Firebase performance as the cause of the crash.

[morganchen12]

Can you symbolicate the hidden/missing symbols in the stack trace?

[google-oss-bot]

Hey @mehulios. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[theScud]

hey google-oss-bot , we are also facing the same crash will upload the symbolicated crash logs

[mehulios]

@theScud Thanks. @google-oss-bot We have only this much details as of now, if we get any more details we will let you know.

does this help ? unfortunately i am not able to get logs from Xcode organiser,

we don't use Ultra SDK, Also a weird thing is there was a spike of crashes on August 14 - 15th after which the numbers dropped down.

i can give you a list of 3rd party libraries (well to a certain extent) if required. Or let me know if there is anything specific like swizzling you want me to look for

[morganchen12]

Thanks, this is very helpful. This line

Invalid type in JSON write (NSURLError)

suggests that the value passed into +[NSJSONSerialization dataWithJSONObject:options:error:] by HyperSDK contains a type that cannot be serialized, ~~which Performance does in order to record network request performance~~.

We can likely fix this on the SDK side by checking if the object is valid JSON before trying to serialize it.

[morganchen12]

It turns out my last comment was wrong and Performance does not call any JSON serializer methods. You should contact the HyperSDK vendor and tell them to fix this issue on their end.

Also, this crash is different from the original crash, which is crashing in -[NSISO8601DateFormatter dealloc] as a result of this exception:

Fatal Exception: NSInvalidArgumentException
*** -[_NSPlaceholderData initWithBase64EncodedString:options:]: nil string argument

[theScud]

Oh okay, Thanks for the info @morganchen12 . i'll reach out to them, apologies if this side tracked the original issue.
