changing shell to bash worked for me

node('node') {

    stage('Something') {
        withCredentials([usernamePassword(usernamePassword(credentialsId: db_id, passwordVariable: 'DB_PSW', usernameVariable:'DB_USER'),]) {
                   sh '''
                   /bin/bash -c '<YOUR SCRIPT HERE>'
                   '''
        }
    }
}

Do this for every line of command
Setting up shebang at the start doesn't help even though it changes the shell
Eg:

sh '''
   #!/bin/bash
   COMMAND1
   COMMAND2
   ........
'''
