If it is a normal exception it is logged with the number of document
where it failed and you can put it on debugger with start=&rows=1
We do not catch a throwable or Error so it gets slipped through.
if you are adventurous enough wrap the RegexTranformer with your own
and apply that say transform
Is there a way to prevent this from occurring (or a way to nail down
the doc which is causing it?):
