This is why it’s good to have unique error codes in addition to messages. It also helps with error monitoring as you can aggregate errors by their error code rather than message (which can have variables in it, different languages, etc).
Error codes can be useful but I find that a lot of vendors using them rely on the code too much to classify errors as identical. Usually the variables do matter, e.g. which file couldn’t be opened or which action was attempted by whom that got a permission denied error.
Error messages are a pain to search for when they are translated too.
