[BUG] Salt Exception with message "Event iteration failed with exception: 'list' object has no attribute 'items'"

Description
We did not change any configuration, so the setup was running before. We want to deploy a Mailserver using Terraform which is calling the salt stack.

When running a High State, we get the following errors:

Minion Log:

Setup

• [ X] on-prem machine
• [ X] VM - Nutanix
• [ X] in combination with Terraform - TF calls the salt stack do deploy an application

The following file is called when the problem occurs:

opendkim.sls:

{%- if pillar.get('opendkim-key') %}
include:
  - base: opendkim

opendkim-schedule:
  schedule.present:
    - function: state.sls
    - job_args:
      - mailserver.opendkim
    - seconds: 21600
    - splay:
        start: 300
        end: 1500
    - run_on_start: false
    - maxrunning: 1
    - jid_include: True
{%- else %}
opendkim-schedule:
  schedule.absent:
    - name: opendkim-schedule
{%- endif %}

Steps to Reproduce the behavior
Run the state either manually or use Terraform.

Expected behavior
Salt Stack should be called, running and deploy the Mailserver as configured.

Screenshots
I don't think they're needed here.
