Fiori for iOS - Validation of authorization code request failed

[#1]

I am trying to run a Fiori for iOS app created through the assistant and I am getting an authorization code request failed error. This is using the latest SDK for Xcode 9.

Below is the log

Hello Eldhose,

Even I faced the same issue, as Andreas mentioned, I have changed my iOS app client ID configuration by comparing it with SAP CP configuration and it's working fine now. Kindly cross verify with your configuration of client ID, redirect URL of your iOS application.

Cheers,

I forgot to mention: in the logs I have the following info message: "The OAuth token is missing in the request"

Hello Garin,

"The OAuth token is missing in the request" - for this error you need to configure OAuth setup in security of your SAP CP application for your account. if settings are done kindly re-check/cross-check with your client ID, redirect URL generation with your content - go app configuration.

Regards,

Jana

Hi Eldhose,

I'm having the same issue, but from the Content To Go app.

Have you been able to solve your issue? If so, I'd be interested in the solution you applied.

I'm having difficulties with the Content to Go application, as I cannot pass the registration stage. I would think that your issue (and mine) are linked to the Auth setup rather than the app itself, but I may be wrong. This error happened once the Cloud Admin changed smth in the Basic Auth setup. Before that I was "just" having a Registration error.

Best regards,

Garin

Eldhose,

This can happen if the client id and redirect URI are not matching up between SAP CP configuration and what you have set up in your iOS app - can you cross-check that please?

Thanks

Hi,

Can you tell the version of your iOS SDK？

Are you using SP01 PL02 or higher? If not, you need to get the higher version to support xCode 9.

Also can you tell what is the system for your iOS device? iOS 10 or iOS 11?

Best regards,

Charlie
