The filter has a regex looking for a literal '{' in the beginning of a line. Some awk implementations interpret this as a meta character, so the regex is deemed broken. Example with busybox awk (POSIX): `root@hank2:~# kamctl ps` `awk: bad regex '^{.+"id"[ ]*:[ ]*[0-9]+[ ]*}$': Invalid contents of {}` `root@hank2:~#` To fix this enclose the character in square brackets. This always matches for a literal '{' and is portable.

I found a (closed) issue and the remedy was to use gawk. But it's actually easy to fix in the regex and when I can run busybox awk I can't save the space which would be needed for gawk. OpenWrt is usually run on embedded so space is often an issue :) Thanks for looking at this!
