I got an error "The GuidRepresentation for the reader is CSharpLegacy, which requires the binary sub type to be UuidLegacy, not UuidStandard."
In some MongoDB instances, even if the "Test Connection" indicates that "Test connection succeeded", some operations in the MongoDB Source or MongoDB Destination might fail, due to the default value CSharplegacy
for GuidRepresentation. To remedy this error, try specifying In the Advanced tab the option uuidRepresentation=Standard
