It looks like having a suite dependency graph is done in the workflow config (suite.rc) file with the following lines:

```plaintext
{%- set scheduledTasks = schedule() | deduplicate_schedule() %}
{{scheduledTasks}}

```

You will need to talk to the suite developers to work out why these jinja2 scripts aren’t working.
