Without MessageID, the Go ADK agent server rejects the message with 'message ID is required' and returns an error with data as an object. The kagent controller's A2A relay (a2a-go/v2) then fails to parse this error since it expects data as an array, causing a -32603 internal error. Setting MessageID: uuid.New().String() fixes the entire chain. uuid is already an indirect dependency in go.mod. Tested with kagent v0.10.1 on EKS (khook v0.0.4).
