    Description

      The logic in the WT error handler in MongoDB is the inverse of what it should be.

      We evaluate if StringData::find() returns non-zero. Instead we should evaluate that it is not equal to std::string::npos, or -1.

      This can confusingly report "An unsupported journal format detected" for all unrelated WiredTiger errors, except for the error it intends on detecting.

      This was caused by a backport of SERVER-35271.
