Custom connector Oauth Authentication issues

Hi Team 

 

I've built a custom connector using Oauth flow but I'm getting an error during authentication:

 

"Sign in

Sorry, but we’re having trouble signing you in.

 
AADSTS650056: Misconfigured application. This could be due to one of the following: the client has not listed any permissions for 'AAD Graph' in the requested permissions in the client's application registration. Or, the admin has not consented in the tenant. Or, check the application identifier in the request to ensure it matches the configured client application identifier. Or, check the certificate in the request to ensure it's valid. Please contact your admin to fix the configuration or consent on behalf of the tenant."
 
I've googled this error and received a few suggestions and references to different articles. One of which says I had to register the application on https://portal.azure.com/ and I did but not sure how would this have any relation to my connector.  Some of the articles are:
 
 
Has anyone faced this error with their Oauth connector and knows of a possible solution.

Hi Zoe

 

Thanks for the reply. 

 

I cannot create a support ticket as i'm not a pro user yet. I'm running on the trial period to see if this works good for our environment and we will move forward accordingly. Unfortunately, I'm struck with the custom data connector authentication issue. Is there an email address that I can use to share the code and get a response?
