multi tenant – Unable to create pluggable database on 19c using response file

I am trying to create Pluggable database using response file but it is giving me below error indicating that one of the mandatory parameters is/are missing. Although I have checked it multiple times and don’t see that any mandatory parameter is missing. Below is my response file which I am using.

 dbca -silent -createPluggableDatabase -responseFile /f01/app/oracle/dbca_pdb_creation.rsp
(INS-04008) Invalid combination of arguments passed from command line. One or more mandatory dependent arguments are not passed for the argument: -createPluggableDatabase

I am able to create the database when passing the required parameters directly in command line as below:

dbca -silent -createPluggableDatabase -sourceDB testcdb  -pdbName testpdb2 -createPDBFrom default  -pdbAdminUserName PDBADMIN  -pdbAdminPassword abcd1234
