[➕ Feature]: don't run workflows when they are not properly configured, until configuration changed

[shahargl]

current behavior When workflow runs without being properly configured, it will cause an error and will try to run again. In case of interval workflow, this will lead to a lot of workflowexecution which will spam the database

expected behavior worklfows that cause configuration error won't run again until they are properly configured

• Let's show some indication in the web that the last execution was not successful

[shahargl]

There is already such indication

[talboren]

@shahargl is this still relevant?

can be fixed by validating yaml on backend and saving status to workflow.is_valid, related to https://github.com/keephq/keep/issues/3903
