Unable to Discover PDB's

Error : 

 Execution of command export TNS_ADMIN=/network/admin;export ORACLE_HOME=; echo "select CDB from v\$database;" |"/bin/sqlplus" -s USERNAME/'*****'@SERVERNAME😕 on host 10.xx.xxx.xxx failed with status 127.

UNIX team granted permission and even created Applicative credentials.

Still no luck

The debug shows, discovery is trying to get exe path from the database and not sure where to set this. We are using Oracle 19 and the TNS_ADMIN path we have is different from what ServiceNow is using in the command (not the ora_home_exe/network/admin)
TNS_ADMIN=" + $ora_home_exe + "/network/admin;
