Claude read an error message that’s benign and now the customer is demanding fixes for something that is not and never has been a problem and won’t actually solve the root issue.

When we started cooperating with a team in India, we had to clean up our logs to reclassify those "errors that are not a problem" because we end up endlessly re-explaining to every new engineer they hire how "ERROR doesn't indicate a problem in this situation." No, writing docs explaining that and assigning said docs as required training ALSO did not help.
