Just the above.

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

I'm having the same issue after updating Firebase pods to 6.21.0.

[paulb777]

Thanks for the reports. We'll investigate.

Does reverting the version of GoogleDataTransport make a difference?

pod 'GoogleDataTransport', '5.0.0'

[aamarkov]

@paulb777 ,

Yes, reverting the version of GoogleDataTransport to '5.0.0' fixed it.

[mikehaney24]

Looking into it. Recently, we changed event URLs to be relative instead of absolute. This problem is likely not a problem for your apps, but it annoying to see these messages, so I'll try to address both of those things in the next day or so. Thanks for the report!

[mikehaney24]

If you clear the app cache, do you still see these errors?

[mikehaney24]

There's several questions I need answered:

1. I need your Podfile.
2. Are you using the 'FirebaseCrashlytics' pod with 4.0.0-beta.6?
   If so, how did you revert GoogleDataTransport back to 5.0.0, because it has a dep on GDT ~> 5.1 which means you can't revert it without reverting the FirebaseCrashlytics pod.
3. Do you still see these errors if you wipe your app's cache? It might be a one-time thing. If it is the one-time thing I think it is, it'll be fixed in the next release by #5187, whereby a derived directory for an event might be figured out, but since the directory doesn't exist, no events are written to it.
4. If it's not this one-off thing above, can you please locally change GDTConsoleLogger.h's line #define GDT_VERBOSE_LOGGING 0 to #define GDT_VERBOSE_LOGGING 1 and send me the log output? If necessary, I can provide a slightly more private communication channel. I'd need this output because I wouldn't know what the problem could be otherwise since I've not been able to reproduce.

[aamarkov]

1. 
   pod 'SwiftLint'
   pod 'Firebase/Auth'
   pod 'Firebase/Database'
   pod 'Firebase/Firestore'
   pod 'FirebaseFirestoreSwift'
2. I'm not using 'FirebaseCrashlytics' pod.
3. I reverted 'GoogleDataTransport' back to 5.1.0, cleared app cache, cleaned Build Folder, and the errors messages were gone. So it was a one-time thing just like you said. Thank you, @mikehaney24 !

[mikehaney24]

Cool, thanks! I'll close then, since it's transient and should be addressed next release.

[gilrodar]

I'm having the same issue with Firebase pods 6.21.0

[paulb777]

Added the next release's milestone to this issue.

[thomtomdup]

Hello.

I have updated all my pods :

Installing Firebase 6.22.0 (was 6.21.0)
Installing FirebaseAnalytics 6.4.1 (was 6.4.0 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing FirebaseCore 6.6.6 (was 6.6.5 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing FirebaseCoreDiagnostics 1.2.3 (was 1.2.2 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing FirebaseCrashlytics 4.0.0-beta.7 (was 4.0.0-beta.6 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing GoogleAppMeasurement 6.4.1 (was 6.4.0 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing GoogleDataTransport 5.1.1 (was 5.1.0 and source changed to https://cdn.cocoapods.org/ from trunk)
Installing GoogleDataTransportCCTSupport 2.0.2 (was 2.0.1 and source changed to https://cdn.cocoapods.org/ from trunk)`

But still have the same problem.
Thank you.
Regards.

[paulb777]

Thanks @thomtomdup - I'll reopen. @mikehaney24 PTAL

[mikehaney24]

Have you tried clearing the app cache as I recommended above?

I need a more specific set of repro steps because I'm not able to with the below steps:

1. Create a new project
2. pod init, add
   pod 'SwiftLint' pod 'Firebase/Auth' pod 'Firebase/Database' pod 'Firebase/Firestore' pod 'FirebaseFirestoreSwift'
   to Podfile
3. Add GoogleService-Info.plist to project
4. [FIRApp configure]; in AppDelegate
5. Run on device

[thomtomdup]

Hello.

I deleted the app. At first start of app no problem displayed but it have these errors when i start another time the app.
This is the first time that I have this problem. When I searched a solution on web, I saw this issue here.

You want that I create a new projet to run it on my phone ? But what will be the final use of it ?

Thank you,
regards.

[thomtomdup]

Do you want that i send you my errors logs file ?

[mikehaney24]

If you can locally change GDTCORConsoleLogger.h's GDT_VERBOSE_LOGGING to 1
(unlock it when Xcode prompts to), re-run, and send me the console log, I'd
appreciate it. Don't forget to change back after running.

Ok. Where can i send it ?

[mikehaney24]

Edit: removed email.

[thomtomdup]

Thank you very much.
I send an email 1 minute ago.

[mikehaney24]

Got it, thanks.

[mikehaney24]

Have you also tried clearing the app cache (uninstall the app and rebuild and run)?

[thomtomdup]

Yes. I did it.

[thomtomdup]

Hello.
This is the same. Errors of removing events always displayed.
I suggest may be to test if the events file exist before delete it no ? This is not the case here.
It's just a suggestion ;-) .

[mikehaney24]

It's reasonable to expect that events could be removed from the cache
unexpectedly because of the inherently transient nature of the app cache.
I'd like to understand why we see that happening in your case since it's
resulting in dropped data, but mostly likely I'll resolve this by silencing
this warning. It doesn't have an effect on the performance of your app.

Yes i think also that will not have an effect on the performance of my app. :)
