Splunk HEC extract value incorrect when there is curly braces in value of key-value pairs.

[cdp_fap]

Using HTTP Event Collector to receier data. When there is unwanted curly brace(s) in value. Event parse incorrect. How can I extract the data when there is {} in the data?

props.conf

SEDCMD-trim = s/{(.*)}/\1/g s/=([^\"].*?)(,|$)/="\1"\2/g

[cdp_fap]

I receiver data via SPLUNK HEC, and the {} is in data, not in the filed name.

[to4kawa]

well, Is it JSON format?

[cdp_fap]

Yes JSON fomat. something like: {key1=value1, key2=value2,....key3="xxxx{yyyyy", keyn1=valuen1}. The curly brace in value3 will result incorrect event parse.

[to4kawa]

please provide actual log. (PII data masking)

your log looks like non-valid JSON.
