We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"

Indendation seems wrong at it should be two spaces character by level so try with something like this regarding indentation issue.

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.
