### Summary In `Settings > General`, when updating a project name to something including a disallowed character, the form simply refreshes without displaying the validation error. ### Steps to reproduce 1. Go to `Settings > General` in a project 2. Update the "Project name" field to `Test Title (Something in brackets)` 3. Click "Save changes" 3. See that update is not made, nor is error displayed ### Example Project Any project. ### What is the current *bug* behavior? When attempting to save with a validation error, the backend returns the error (see AJAX response below). However, the frontend does not display this error to the user. ### What is the expected *correct* behavior? The frontend should display the error which the AJAX request returned. ### Relevant logs and/or screenshots Response from `POST https://gitlab.com/group/project` endpoint: ``` $(".project-edit-errors").html("<div class=\"alert alert-danger\" id=\"error_explanation\"><h4>The form contains the following error:<\/h4><ul><li>Name can contain only letters, digits, emojis, &#39;_&#39;, &#39;.&#39;, dash, space. It must start with letter, digit, emoji or &#39;_&#39;.<\/li><\/ul><\/div>\n"); $('.save-project-loader').hide(); $('.project-edit-container').show(); $('.edit-project .js-btn-success-general-project-settings').enable(); ``` ### Output of checks This bug happens on GitLab.com.
