How the result is calculated
An in-page knowledge base of rules: a regex pattern + keywords + a weight. A rule’s score = its weight if the pattern matches + the number of keywords present (without a pattern at least two keywords are required). Rules are ranked by score and the top three shown. Confidence = score ÷ (score + 6) as a percentage — a heuristic indicator, not a statistical probability.
Limits:
The base covers common errors only (the rule count is shown on the page); an error that is not listed will not be diagnosed. The cause is “likely”, not certain — the same message can have other causes. It cannot see your workflow or execution data.
FAQ
Why was no rule found?
The base is limited; paste the full message including the status code.
What does confidence mean?
A heuristic indicator of match strength, not a probability.
