jq: error: syntax error, unexpected $end, expecting QQSTRING_TEXT or QQSTRING_INTERP_START or QQSTRING_END (Unix shell quoting issues?) at , line 1:
.resources[] | select(.name| contains ("NiFi

command

export pg_id_string=echo $resources| jq -c '.resources[] | select(.name| contains ("'$pg_name'")) | .identifier' | grep -v 'data|policies|operation' | grep'process-groups' | tr -d '"'``

Below are the troubleshooting steps i have done from previous issue/query.
