Error caused by gpg.import_key in soloist state file

I am getting a strange error in the salt state file when I try to import a GPG key using this state file. Interestingly, the key was imported correctly into GPG.

gpg.import_key_public:
  module.run:
    - name: gpg.import_key
    - user: ubuntu
    - text: |
        {{ salt['pillar.get']('gpg:public_key', '') | indent(8) }}
    - require:
      - pip: python-gnupg

      

        
        
        
      

    

I am getting the following error:

          ID: gpg.import_key_public
    Function: module.run
        Name: gpg.import_key
      Result: False
     Comment: Module function gpg.import_key threw an exception. Exception: list indices must be integers, not str
