thiemowmde moved this task from Sprint Backlog to Done on the WMDE-TechWish-Sprint-2025-06-25-Basil-Lime-Sorbet board.

I'm confused how something mundane as this can be an "unbreak now"? It impossible to cause any harm other than being logged.

Our policy is to reduce the stream of logged errors to a minimum so that ideally there is nothing being logged. This way we can detect errors more easily (that is not automated). We file tasks for new errors and flag them as train blockers and unbreak now to ensure they get triaged. In most case the train conductor barely know the code or what effect it can have.

That got triaged and even fixed!!! I'll deploy it. Thank you :)
