"TypeError: update expected at most 1 arguments, got 2"

I’m running a simple playbook from within Ansible Tower but getting the error in the subject line.

Version info:

  • Tower server: RHEL 7.5, Ansible 2.5.3, Ansible Tower 3.2.2
  • Remote node: RHEL 7.5

The playbook has multiple hosts sections, all are defined like this (with line numbers):

21 - name: “Setup the testing TEST/DEV systems”
22 hosts: test_dev
…
63 - name: “Setup the testing PPROD/PROD systems”
64 hosts: test_prod
…

103 - name: Setup of test systems

104 hosts: test_sys

The “test_sys” group is just a collection of the “test_dev” and “test_prod” groups. The first two work just fine and gather facts, but the third errors out in the “Gathering Facts” step (lines truncated for length marked with ‘snip’):

Any ideas where to start looking?

Dan,

This looks to me like a bug in Ansible itself, rather than awx.

Dan,

For help with Ansible, you might try the Ansible mailing list:https://groups.google.com/forum/#!forum/ansible-project

Or the Ansible IRC room on freenode (ansible)

Based on your usage of Ansible Tower, you might also consider reaching out to your account representative at Red Hat (this mailing list is specifically for the open source awx project).

I’d agree, but when I run the playbook from the command line that error doesn’t come up so I’m suspecting something with the AnsibleTower-AnsibleCore interactions.

I’ll open a ticket with RedHat support to see what they say.
