Getting an error when trying to connect via Facebook

James,

Matias here, from Auth0. We'll look into this.

In the meantime, can you do a quick test? In Auth0Client.m there is a parameter sent to our API: scope=openid%%20profile (https://github.com/auth0/Auth0.iOS/blob/master/Auth0Client/Auth0Client.m#L21). Can you try removing the %%20profile? I think this probably has to do with Facebook returning a big profile and the token we generate is too large. Let's try that.

[parkej60]

That seems to have removed the error. Does this mean that the profile information won't be returned at all now?

[woloski]

No, we can use the API (/userinfo endpoint) to retrieve the user profile instead of getting it back in the token.

BTW, other customers deleted some of the attributes coming from Facebook that weren't useful in their scenario by using a rule in Auth0.

[woloski]

@parkej60 we updated the library to use the /userinfo endpoint. Let us know if you find any other issue.

Thanks for all the feedback!

This is an unrelated error, but I'm having issues with the block calls withing the webview delegate method. It needs a bool returned and it seems to not call any code that follows the block call within it. I'm wondering if it has something to do with your files be non-arc. I'll continue to troubleshoot it and let you know what I find, but if you have any insight please let me know.

[woloski]

We added a sample as well (https://github.com/auth0/Auth0.iOS/tree/master/Auth0Client.Sample). If you try that, do you get any errors/issues?

I'm now getting this error.

Hi James, where are you getting that? I just tried the sample on ios7 emulator and it worked fine.
By the way, we are on the chat http://chat.auth0.com if you want to connect there.

[parkej60]

I still get the Facebook error message that I originally posted when using your example app. Also it appears that your example application is using the compiled library? Is that what I'm supposed to be using or should I just be using the class files?

[woloski]

Yes. I've got that error as well the first time you log-in with Facebook. It's an alert view that is shown when there is a URL that can't be resolved. We are removing that alert and just leaving the NSLog. Also, the sample was pointing to the library, as you mentioned, we are changing it to point straight to the src code.

Apologies for all the back and forth with this. Although these SDKs are open source so anyone can fix things, we are responsible for them and want them to be straight forward, otherwise it gets frustrating as a developer. So thanks for helping us making this SDK more robust for the next dev 😃

[parkej60]

Thanks, I appreciate your quick responses as well. It definitely makes it easier and more reassuring.

[parkej60]

Oh, when you're fixing the sample project you probably want to pull out all non-relative path references as well. I had to remove one that was referring to your devs local machine.

[woloski]

yep, saw that :)
