Task is delayed indefinitely without any errors or any log output at all

[p-weisk]

I have configured a task to run every 5 minutes like this:

Flowpack:
  Task:
    tasks:
      'Example.Taskname':
        label: Label
        description: My example task
        handlerClass: 'Class\That\Exists'
        cronExpression: '*/5 * * * *'
        workload:
          interval: PT6M
          jobs: 'log,visit'

The task is created in the database and scheduled with a next run. However, it is never started and does not create any error output in task:list or task:show or the Flow System log. If I run the code the task would execute manually, it works.

This is the anonymized oputput of task:list :

+-------------------------------+-----------------------------+-----------------+---------------------------------------------------------------------------------+-------------------+---------------------+-----------------------+-------------------------------+
| Identifier                    | Label                       | Cron Expression | Handler Class                                                                   | Previous Run Date | Previous Run Status | Previous Run Duration | Next Run                      |

+-------------------------------+-----------------------------+-----------------+---------------------------------------------------------------------------------+-------------------+---------------------+-----------------------+-------------------------------+

and task:show :

|                 | }                                                                               |

Task Executions
This task has not yet been executed.

I tried deleting the entry in the database, flushing caches and then scheduling it again with task:run. It recreates the task entry in the database but the delay persists.

Is there any way to diagnose why it is delayed?

Setup:

PHP 8.4.16
Flow 9.0.5
flowpack/task 1.2.1
