FIRAuthInternalErrorDomain "MISSING_IDENTIFIER" when trying to login with custom token

[Dylan]

I've recently migrated to the new version of Firebase. I'm using the new SDK in my iOS app.

I'm using Firebase 3.2.0 and have hit the following error when sign in with custom token:

Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={NSUnderlyingError=0x7fd290f3dc50 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey=<CFBasicHash 0x7fd2931787a0 [0x10e5db7b0]>{type = immutable dict, count = 3,

entries =>

0 : <CFString 0x7fd2931669b0 [0x10e5db7b0]>{contents = "message"} = <CFString 0x7fd29318e280 [0x10e5db7b0]>{contents = "MISSING_IDENTIFIER"}

1 : errors = <CFArray 0x7fd2931554b0 [0x10e5db7b0]>{type = immutable, count = 1, values = (

0 : <CFBasicHash 0x7fd293141000 [0x10e5db7b0]>{type = immutable dict, count = 3,

entries =>

0 : reason = invalid

1 : message = <CFString 0x7fd2931a0070 [0x10e5db7b0]>{contents = "MISSING_IDENTIFIER"}

2 : domain = global

}

)}

2 : code = <CFNumber 0xb000000000001903 [0x10e5db7b0]>{value = +400, type = kCFNumberSInt64Type}

}

}}, error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})

I don't know what "MISSING_IDENTIFIER" means.

Does anyone have the same issue?

Dylan,

What version? What does your custom token gen code look like? What are the payload used to create the token?

By the way, there is a good summary of the claims needed at the bottom of this thread.

It's possible you are using a custom token from the old token generators for the 2.x.x SDKs, and not the new token generators for the 3.x.x SDKs. You can read these docs to learn how to create custom tokens for the new SDKs.

As Kato mentioned, we need some more info to help you out, including how you created the custom token and what code you are using to get this error.

Cheers,

Jacob
