There was a problem hiding this comment.
No, this is bad practice to return exception details to client for unknown generic exceptions, as it can expose sensitive implementation details.
It would be fine to log the original exception though when wrapping in generic message.
Even without patch, the model code can use mms.PredictionException to preserve error code and message (see line 109 just a few lines above this)
