The code to display HMR errors on the client was reading the `description` field from Metro payloads. Metro does not include `description` in the body of its error payloads -- only in its `body.errors[]` items. This commit changes RN's HMR code to show `body.message` (set consistently with facebook/metro#124) instead of the non-existent `body.description`. Test Plan: Open a test RN app, enable HMR, and then introduce a syntax error in an app source file. See that the redbox provides information about the syntax error instead of just saying "TransformError undefined".

When I simplified
I then tried identifying other places where description was used, but I obviously not looked exhaustively 😅. Thanks for pointing out that one and fixing it! |
