I'm creating a pipeline with a gsub processor and I keep getting this error when testing the pipeline on a document. I had to add a unique delimiter before ingesting to deal with a whitespace issue. I'm now trying to replace that delimiter with white spaces. The delimiter is |x| and my configuration for the gsub processor is
^\\|x\\|$. I would use "ignore_failure" but then the processor will never truly work if it can't find the field I'm trying to modify.
