Why is the sync module hanging in Ansible Automation Platform?

Issue

• While running a playbook using the synchronize module in Ansible Automation Platform the Job Template is hanging and there are no errors:

• Using the posix.synchronize module, the playbook hangs (no errors, runs indefinitely).

• Other Ansible modules work fine.
