SetUserContext doesn't work on IOS 10.4.3

[OlivierNguyen]

I wrapped setUserContext into function and call it in the ComponentDidMount of my app.

export const sentrySetUserContext = (user) => {
  Sentry.setUserContext(getUserInfo(user));
};

const getUserInfo = (user) => ({
  userID: user.id.toString(),
});

To test, I add a button which calls Sentry.nativeCrash().
I received the error in the Sentry console but without information about UserID.
It only shows my IP.

IOS version: 10.4.3
Sentry version: 0.21.1

I did not test on Android.

Hey, can you enable verbose logging:

Sentry.config("DSN", {
  logLevel: SentryLog.Verbose
}).install();

You should see a output similar to this:

'react-native-sentry (setUserContext):', { userID: '12341' }

I wasn't able to reproduce this, please make sure your setUserContext is called.

I see the output:
but on the website (Sentry console), i did not see theses informations.

I created a new project using create-react-native-app and did the same steps, and it seems to work. I'll investigate more to understand what happened.

Thanks you

I still don't know why the userID is not shown in the Sentry console.

Is it possible to see easily the content that is sent to your Sentry server when a crash occurs ? It seems that the information about user is lost, but i do not know where.

Thanks

I come with some insights:

Using Charles, I saw a difference in the body request between my app (which doesn't work) and the mini-app (which works).
The function called on both app is :

Sentry.setUserContext({ userID: "12345", extra: { country: 75 } })

Content of data sent to Sentry API in my App (not working):

"user": {
		"id": "12345",
		"username": "(null)",
		"email": "(null)",
		"extra": {
			"country": 75,
		}
	}

And content of data sent to Sentry API with mini-app (works):

"user": {
		"userID": "12345",
		"extra": {
			"country": 75,
		}
	}

I don't know why it added "username" and "email" keys and set them to "(null)". Because "(null)" is not a valid email, it won't display the user context in the Sentry console.

My little fix was to set username and email with fake values in setUserContextfunction.

I'm using Sentry@0.21.2 and IOS10.3.1

Thank you very much for investigating this so thoroughly, I will release a fix for this soon.
