The failure handler for
runTranslationcurrently shows a generic error message and ignores the specific error details (msg) returned from the server. This makes it difficult for users to understand what went wrong. To improve user experience, you should display themsgcontent in the error message, similar to how it's done inrunAllTranslation's failure handler.
