This absence did not create an observed issue, but it seems like we should invoke replyHandler here.

Noticed a Sentry report. It could be unrelated, but this might fix it: JETPACK-IOS-1JEE |

What?
Ensures that
EditorAssetBundleProvideralways calls thereplyHandlerwhen handling JavaScript message requests, even when an error occurs.Why?
When
getEditorRepresentation()throws an error, thereplyHandlerwas not being called. This would leave JavaScript waiting indefinitely for a response that never comes, potentially causing the editor to hang or behave unexpectedly.How?
Added the missing
replyHandler(nil, error.localizedDescription)call in the catch block ofuserContentController(_:didReceive:replyHandler:).Testing Instructions
