Hi everyone,

I'm getting this error while creating an endpoint for a business event in D365FO. I'm giving /Azure service bus queue/ as endpoint type, then I'm filling out the endpoint name, description, queue name from azure portal (Service bus namespace's queue name), then Microsoft application Entra ID, then the secret value we create in /certificates & secrets/ from azure portal, key vault's URI, and the key vault's secret's name which is holding connection string from service bus.

Response status code does not indicate success: 400 ({/error/:/invalid_client/,/error_description/:/Expected aud https://securityservice.operations365.dynamics.com but found ./}).

Hi,
This error is mentioned in the documentation on business event troubleshooting, which mentions that the error occurs because cloud-hosted environments and on-premises environments (also known as Local Business Data [LBD] environments) do not use security services. You can view this document and follow the steps in the document to complete the setup manually:

Best Regards,
