Hello, this is meant as feedback to elastic:
All of a sudden yesterday my entire cluster (thankfully not my production cluster) started bombing out "regular expression has redundant nested repeat operator" errors, after a few minutes on google I learned it had something to do with pipelines, the error messages I get are ..... bad
The problem is, I don't get the name of the pipeline and I have 180 pipelines, so I tried deleting them all and importing them again to see if the problem lies there, which it does.
now I am manually auditing 180 pipelines by hand, simply getting the name of the pipeline in the error message would save me several hours of work (so far) and a cluster crash
