Declarative pipeline - Running a shell command

Question

I have a jenkins pipeline script that I am updating wish to use the following shell command:

sh script: """
  export PATH=\"${PATH}\":\"${WORKSPACE}\"
  BASE_DIR=$(dirname $0)
  source "${BASE_DIR}/shellscript.sh"
                               
  helm uninstall ${helmReleaseName}  --namespace ${kubenamespace} 
"""
             

And the result always is:

Errors encountered validating Jenkinsfile:

I've played around with it. But it fails the validation? The question is why?

Thanks

Declarative pipeline with 'sh' step will look like:

stage ("Preparing") {
    steps {
        sh'''
          export PATH=\"${PATH}\":\"${WORKSPACE}\"
          BASE_DIR=$(dirname $0)
          source "${BASE_DIR}/shellscript.sh"
                               
          helm uninstall ${helmReleaseName}  --namespace ${kubenamespace}
        '''
    }
}
