🔥[iOS] _reactNativeFirebase.default.crashlytics().log is not a function

[svenlombaert]

Issue

I'm upgrading Crashlytics to the latest version. Everything works fine on Android, so that's good. On iOS I get logs that Crashlytics is initialising and I can set the userIdentifier without any problems.

When I try to log something though, I run into this error:

_reactNativeFirebase.default.crashlytics().log is not a function. (In '_reactNativeFirebase.default.crashlytics().log("We're about to force a crash")', '_reactNativeFirebase.default.crashlytics().log' is an instance of Object)

So, next thing I did was logging the crashlytics().log function, and this, weirdly enough, showed that log() is an object with 4 functions inside:

'crashlytics().log: ', { debug: [Function: debug],
  info: [Function: info],
  warn: [Function: warn],
  error: [Function: error] }

I then started logging other functions like recordError and recordCustomError, but they all seem to be fine.

same issue happens in v6

[svenlombaert]

@wamry Have you been able to fix this yet by any chance?

[jvandenaardweg]

Same issue on a clean install of v6.

Temporary workaround, use it like this:

crashlytics().log('some log!')
crashlytics().crash()

edit: seeing other react native firebase modules, i think the docs are incorrect and above is the proper way to use the module.

[Ehesp]

Thanks, just pushed up a fix to the docs, should go live soon 1570690

[svenlombaert]

@Ehesp can you reopen this issue? I was not talking about the docs at all and am using the module correctly.

[svenlombaert]

Replying here again, this issue has been closed whilst the problem still exists. I am using the module correctly. @Ehesp

[EgorFrom]

Hi @svenlombaert , i have this problem. If it can help you. I change

import * as crashlytics from '@react-native-firebase/crashlytics';

to

import crashlytics from '@react-native-firebase/crashlytics';

and it is work

[svenlombaert]

I upgraded to v6 and all seems to work now 👍
