Help with grok filter on ingest pipeline

[RaonyO (Raony Oliveira)]

Hello, I'm trying to use the following grok filter, but I'm getting a message saying it's in an invalid json format, but I think my filter is written correctly. can you help me with this?
filter:

(%{TIMESTAMP_ISO8601:time})%{NOTSPACE} firewall: msg_id=\\"%{DATA:msg_id}\\" %{DATA:action} %{DATA:source} %{DATA:if} %{DATA:number1} %{DATA:protocol} %{DATA:number2} %{DATA:number3} %{IP:srcip} %{IP:destip} %{NUMBER:srcport} %{NUMBER:destport} offset %{NUMBER:number4} %{DATA:word1} %{NUMBER:number5} win %{NUMBER:number6}%{SPACE}signature_name=\\"%{DATA:signature_name}" signature_cat=\\"%{DATA:signature_cat}" signature_id=\\"%{DATA:signature_id}\\" severity=\\"%{NUMBER:severity}\\" sig_vers=\\"%{NUMBER:sig_vers}\\"%{SPACE}geo_src=\\"%{WORD:geo_src}\\"%{SPACE} geo_dst=\\"%{WORD:geo_dst}\\"%{SPACE}msg=\\"%{DATA:msg}\\"%{SPACE}%{GREEDYDATA:msg2}

obs: I'm using the ingest pipeline menu in kibana

Your pattern seems to pass validation for me. Did I miss something in your request?

[RaonyO (Raony Oliveira)]

I performed the same test and it didn't pass the validation, anyway I'm using an old version of elk (7.13) could that be the reason for not validating?

[drewdaemon (Drew Tate)]

Hmmm, yeah, that's possible. I'm on the latest (8.6).

I put the same filter on a newer version and it worked, that's probably it, thanks anyway!
