GraphAPI Error: Application is not registered in our store

[gabdelgadoawsys]

I am currently getting the following error message from the GraphAPI:

Status Code: Forbidden
Microsoft.Graph.Communications.Core.Exceptions.ServiceException: Code: UnknownError
Message: {"errorCode":"7503","message":"Application is not registered in our store.","instanceAnnotations":[]}
Scenario Id: 4e4815b3-05c7-4e08-a0a2-0c9064289a05

Thanks to @itisslizz and @1fabi0 , I was able to get rid of the following error:

Microsoft.IdentityModel.Clients.ActiveDirectory.AdalServiceException: AADSTS700016: Application with identifier <APP ID> was not found in the directory <TENANT ID>.

from this issue: #426

Current Setup

1. Tenant A contains the fully configured Azure Bot Service.
2. Tenant A has no 365 subscription (including Microsoft Teams)
3. Tenant B has the 365 subscription (including Microsoft Teams).
4. Tenant B has no Azure subscription.

Additional Notes:

1. The bot service app (in Tenant A) has admin consent and permissions granted in Tenant B.

Any recommendations for this?

I have the same error message with only one tenant when bot tries to join a meeting...how did you solve the problem on the same tenant?

Please make sure you enabled calling on your bot registration and have a url in the field that can be called

Enabled calling and also gave callbackuri in the field. Still I am getting the same error "Application is not registered in our store".

Request body: { "@odata.type": "#microsoft.graph.call", "callbackUri": "https://contoso.com/teamsapp/api/calling", "targets": [ { "@odata.type": "#microsoft.graph.invitationParticipantInfo", "identity": { "@odata.type": "#microsoft.graph.identitySet", "user": { "@odata.type": "#microsoft.graph.identity", "displayName": "ABC", "id": "1" } } } ], "requestedModalities": [ "audio" ], "callOptions": { "@odata.type": "#microsoft.graph.outgoingCallOptions", "isContentSharingNotificationEnabled": true }, "mediaConfig": { "@odata.type": "#microsoft.graph.serviceHostedMediaConfig" } } Do I need to add any other additional paramter?
