Resolve 'Rebase fails with "something went wrong" and huge ugly conflict error.' (!16326) · Merge requests · GitLab.org / GitLab FOSS · GitLab

Jan Provaznik requested to merge 4020-rebase-message into master Jan 09, 2018

What does this MR do?

It stores and displays generic error message if rebae fails instead of long detailed backend error.

Why was this MR needed?

A details backend error was displayed to user when rebased failed. This was both ugly and exposed details about backed setup.

Closes #41820 (closed)
