<!--- Please read this! Before opening a new issue, make sure to search for keywords in the issues filtered by the "regression" or "type::bug" label: - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=regression - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=type::bug and verify the issue you're about to submit isn't a duplicate. ---> ### Summary <!-- Summarize the bug encountered concisely. --> Creating a new value stream with new duplicate custom stage names results in a 500 error due to `UNIQUE` constraint. ### Steps to reproduce <!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. --> 1. Create/edit value stream 2. Add two custom stages with the same name 3. Submit form ### What is the current _bug_ behavior? <!-- Describe what actually happens. --> Form submission is stuck, and no errors are displayed in the UI. ### What is the expected _correct_ behavior? <!-- Describe what you should see instead. --> Form is allowed to submit and errors should be displayed upon backend/frontend validation. ### Relevant logs and/or screenshots <!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's tough to read otherwise. -->  ```plaintext ActiveRecord::RecordNotUnique at /groups/toolbox/-/analytics/value_stream_analytics/value_streams/23 ==================================================================================================== PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_group_stages_on_group_id_group_value_stream_id_and_name" DETAIL: Key (group_id, group_value_stream_id, name)=(22, 23, Cool) already exists. > To access an interactive console with this error, point your browser to: /__better_errors lib/gitlab/database/load_balancing/connection_proxy.rb, line 127 ---------------------------------------------------------------- ``` ruby 122 if read_only_transaction? 123 raise WriteInsideReadOnlyTransactionError, 'A write query is performed inside a read-only transaction' 124 end 125 126 @load_balancer.read_write do |connection| > 127 connection.public_send(...) 128 end 129 end 130 131 private 132 ``` <details><summary>App backtrace</summary> ``` ------------- -

~frontend Handle anything other than success with a relevant message rather than an infinite spinner :point_right: #415512 - ~frontend Add a validation on the frontend to detect duplicate stage names in the form (create and also on edit) :point_right: #415513 -
