HI, I'm trying a very simple grok pattern and in Grok Debugger it works fine: ![Screenshot from 2020-10-24 15-19-30](https://us1.discourse-cdn.com/elastic/original/3X/c/4/c43fb164678aea27460d8d7ea6ab85952c593d45.png) But when I tried the same pattern in ingest pipeline I got this "Bad String" Error: ![Screenshot from 2020-10-24 15-21-16](https://us1.discourse-cdn.com/elastic/original/3X/1/0/10e9e09b2ec787451ec469d55751e417d64f75a6.png) Any idea why? I'm using ELK 7.9.2 ---

I think you might have to write ``` \\[%{WORD:test}\\] ``` ---

> [@dadoonet](#): > > `\\[%{WORD:test}\\]` Yep, this works fine. So what's the reason for different behavior between `Grok Debugger` and `Grok Processors` with escape characters? ---

I believe the Grok Debugger UI does the magic for you where the http rest API can not. ---

Hmm. interesting. Also there's something wrong with the ingest pipeline UI. Here I config my processor and there is no error: ![Screenshot from 2020-10-26 10-01-51](https://us1.discourse-cdn.com/elastic/original/3X/9/2/92b61f1bf03283baf01e880dba0aa78d960daf53.png) I test it with `test pipeline` option and it works. but when I want to edit my processor it looks like this: ![Screenshot from 2020-10-26 10-02-08](https://us1.discourse-cdn.com/elastic/original/3X/3/e/3e619da76336d8ffde41d604c312fc38e7376917.png) the pipeline still works but the config looks weird. and if I add a custom pattern (`"TESTWORD" : "\b\w+\b"`) it will change to this which is unreadable : ![Screenshot from 2020-10-26 10-13-07](https://us1.discourse-cdn.com/elastic/original/3X/d/0/d0e4e20404eede18fc3cf63dcd6169666535d9b9.png) Is this a bug or this is normal? P.S: In preview window in `Ingest Node Pipelines` page it's showing correctly: ![Screenshot from 2020-10-26 10-40-15](https://us1.discourse-cdn.com/elastic/original/3X/c/c/cc25b106937a039341470bb5d965c232852126bc.png) ---

I don't know but I moved the discussion to #elastic-stack:kibana where folks might tell if it should be reported as an issue in GitHub. ---
