Call Runtime-Server OnlineService using Azure Synapse Hello, I have a runtime-server online service that I am trying to call using Azure Synapse using OAuth authentication. I created a REST Linked Service in Azure that connects successfully to the runtime-server online service. I am using a copy activity in Azure to do a POST call on the online service. When running the copy activity I get the following error: { "errorCode": "2200","message": "Failure happened on 'Source' side. ErrorCode=UserErrorCharSetInvalidOrNotSupported,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=The CharSet '\"UTF-8\"' is invalid or not supported from Response.Headers.Content-Type.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.ArgumentException,Message='\"UTF-8\"' is not a supported encoding name.
