An Error Message Is Information, Not A Verdict
The machine is trying to help, in a flat and unfriendly register, and reading it properly saves hours.
The instinct when something fails is to flinch, skim, and start changing things. This is understandable and almost always wrong. An error report is the most direct evidence you will get, produced at the exact moment the trouble surfaced, describing what was being attempted and where. It is written in a tone that reads as accusatory only because it is written by something with no tone at all. It is not judging you. It is telling you what it could not do.
Read it slowly, from the top, in complete sentences. Identify three things: what was attempted, what was expected, and where it happened. Then notice that where it happened is where the problem became visible, not necessarily where it began. Something set up the wrong conditions earlier and the failure appeared at the first step that could not tolerate them. Working backwards from the visible point to the origin is the actual investigation, and it starts by taking the message at its word.
If a message is genuinely unclear, that is worth naming rather than absorbing as personal failure. Look up the unfamiliar terms, one at a time. Vocabulary is finite and repeats endlessly, so an hour spent understanding a category of message today is repaid many times over. Over a few months of doing this, messages stop reading as noise and start reading as a colleague saying, quite precisely, exactly where they got to before they could go no further.
