provider.SignInWithOAuth() throws exception. about firebase-authentication-dotnet

[bezysoftware]

Can you try the latest version of the package (v2.0.1)? In case of an error it throws a FirebaseAuthException which should contain all information you should need to debug it (target url, post data and most imporantly responseData, which should contain the reason for the error).

[achabill]

Thank you for the update.

I get "invalid key" as reason in exception.
Here is what I have, don't know where I am going wrong.
Privacy of keys does not matter. It's all for testing purposes.

The first option gets the idtoken from Auth0 and creates the fireabse token with firebaseAuthentication
The second option generates the firebase auth token from Auth0 .

//KEYS AND IDs

I've also tried generating the access token using winfbsdk (which worked well) before passing in SignInWidthOAuthAsync(). Getting the same results.

I've checked all loose ends. Don't know what is causing this. Maybe I'm not using the tokens or keys correctly.

[bezysoftware]

I never worked with Auth0 so I'm not sure what kind of tokens it generates. Check out the samples (I just pushed them), they may help.

[ngducnghia]

I have similar problem.

{
"error": {
"errors": [
{
"domain": "usageLimits",
"reason": "keyInvalid",
"message": "Bad Request"
}
],
"code": 400,
"message": "Bad Request"
}
}

var firebase = new FirebaseClient("https://myapp.firebaseio.com/"); var authProvider = new FirebaseAuthProvider(new FirebaseConfig("myFirebaseScerectMechmFmi6")); FirebaseAuthLink authEmail = await authProvider.CreateUserWithEmailAndPasswordAsync(username, password);

[ngducnghia]

I think the problem is with the Legacy Firebase App, I created another one and it does works for me.
@bezysoftware can you confirm this?

[bezysoftware]

Can I still create "legacy" app in the current Firebase console?

[ngducnghia]

Yes I can still create using my current Firebase legacy account, not sure if you can still create new account. It's on https://www.firebase.com/
