Media Services API 2020-05-01 returns 400 rather than 404 when a private endpoint connection cannot be found

Hi there, it appears the Media Services API returns a 400 instead of a 404 when a PrivateEndpointConnection does not exist.

> media.PrivateEndpointConnectionsClient#Get: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadRequest" Message="Private endpoint connection name is not valid"

Can this be fixed?

Thanks!

Start by locating the Media Services API 2020-05-01 specification and its PrivateEndpointConnection GET operation. Compare the documented behavior for a missing connection with the reported 400 response. Done means the API behavior or specification clearly represents a missing private endpoint connection as 404, with any applicable validation captured.
