While trying to deploy whatsapp-bridge the followin task fails:

TASK [custom/matrix-bridge-mautrix-whatsapp : Ensure mautrix-whatsapp config.yaml installed] ************
fatal: [matrix.myserver.de]: FAILED! => 
  msg: |-
    An unhandled exception occurred while templating '{{ matrix_mautrix_whatsapp_configuration_yaml | from_yaml | combine(matrix_mautrix_whatsapp_configuration_extension, recursive=True) }}'. Error was a <class 'yaml.scanner.ScannerError'>, original message: while scanning a simple key
      in "<unicode string>", line 18, column 1
    could not find expected ':'
      in "<unicode string>", line 19, column 5

To Reproduce
The relevant part of my vars.yml file looks like this:

matrix_mautrix_whatsapp_enabled: true
matrix_mautrix_whatsapp_bridge_encryption_allow: true

Running ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start

Expected behavior

Sounds like you may be on an old version of Ansible or Jinja

Hey - thanks for the quick reaction!

Interesting - I am currently using

ansible==9.2.0
ansible-core==2.16.3
Jinja2==3.1.2
PyYAML==6.0.1

installed via ubuntu apt-package.

I will try and user a newer version of Ansible via pip.

Hey - so same error sadly - I set up a fresh venv:

  msg: |-

pip freeze

I can't ...

I added debug tasks to the whatsapp role to see the yaml blocks before merging them only to see that I had unresolved git-merge errors in my jinja-template file, which obviously made yaml crash -.-

and surprise - after fixing that it works.

Sorry for even bothering you and thanks. I will close this
