I have the following ansible code:

“`

- name: Install and configure PGS servers for RZ
  hosts: pgs_rzdb_servers
  tasks:
    - name: Prepare pgs_server role variables
      set_fact:
        pgs_server_custom_role_vars: >-
          {{
            {
              'pgs_server_version': pgs_rzdb_server_version,
              'pgs_server_port': pgs_rzdb_server_port,
              'pgs_server_pg_hba_rules': pgs_rzdb_server_pg_hba_rules,
              'pgs_server_max_connections': pgs_rzdb_server_max_connections,
              'pgs_server_idle_in_transaction_session_timeout': pgs_rzdb_server_idle_in_transaction_session_timeout,
              'pgs_server_marker': 'RZDB'
            }
            | dict2items
            | selectattr('value', 'defined')
            | items2dict
          }}

    - debug:
        msg: "Role variables: {{ pgs_server_custom_role_vars }}"

    - debug:
        msg: "Role variables: {{ pgs_server_custom_role_vars | type_debug }}"

    - name: pgs_server
      import_role:
        name: pgs_server
      vars: "{{ pgs_server_custom_role_vars }}"
      tags:
        - pgs_server

Even though I get the following debug messages when I comment out vars:

TASK [debug] ************************************************************************************************************************************************************************************************************************************** ok: [lspostgres02.ls.local] => { "msg": "Role variables: {'ls_pgs_server_version': 13, 'ls_pgs_server_port': 5431, 'ls_pgs_server_pg_hba_rules': [{'contype': 'host', 'users': 'all', 'source': 'lxserver.ls.local', 'databases': 'all', 'method': 'md5'}, {'contype': 'host', 'users': 'all', 'source': '192.168.69.0/24', 'databases': 'all', 'method': 'md5'}], 'ls_pgs_server_marker': 'RZDB'}" }

TASK [debug] ************************************************************************************************************************************************************************************************************************************** ok: [lspostgres02.ls.local] => { "msg": "Role variables: dict" }

when I uncomment this line I get the following error:

ERROR! Vars in a IncludeRole must be specified as a dictionary

The error appears to be in '/mnt/c/Users/dhe/Documents/Checkouts/ls-ansible/ls_pgs_rzdb_servers.yml': line 30, column 13, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

        name: pgs_server
      vars: "{{ pgs_server_custom_role_vars }}"
            ^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

Is this a bug, or what am I doing wrong here?

I’m using ansible [core 2.16.6]

I expect this to just work correctly, because the documentation of ansible tells me, that I have to pass
Dictionary/map of variables here.
