An unhandled exception occurred while templating

[o-]

I tried to run this in a fairly standard configuration on fedora 32, ansible 2.9.17 and I get the following error:

TASK [matrix-synapse : Ensure Synapse homeserver config installed] ********************************************************************************************
fatal: [xxxx]: FAILED! => {"msg": "An unhandled exception occurred while templating '{{ matrix_synapse_configuration_yaml|from_yaml|combine(matrix_synapse_configuration_extension, recursive=True) }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: An unhandled exception occurred while templating '{{ matrix_synapse_configuration_extension_yaml|from_yaml if matrix_synapse_configuration_extension_yaml|from_yaml is mapping else {} }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: Unexpected templating type error occurred on ({{ matrix_synapse_configuration_extension_yaml|from_yaml if matrix_synapse_configuration_extension_yaml|from_yaml is mapping else {} }}): a string or stream input is required"}

Unfortunately I don't really know how to debug this

Run your vars.yml file through a yaml linter like http://www.yamllint.com/, make sure to redact the secret keys before you paste it in. It looks like you’ve made some invalid YAML. If that doesn’t work then paste your config here so we can see it.

Thanks a lot for your time. So the yaml seems valid. Here you go:

Actually, just to narrow down the problem, I removed all the jitsi stuff and I re-ran from scratch and I get a slightly different error earlier. Though I believe in the previous run, with the error reported above, I just commented out this task to get further....

@o- Don't post those secret keys and passwords. You are going to need to change those now.

Run git status and show the output.

Sure, no worries, I know. I am just experimenting at this point.

Run git status and show the output.

I am on master, commit 66064f0890852aed069a003be6be53a98f93118f no local changes

[aaronraimist]

@o- Hmm. Then I'm guessing it is an Ansible bug. Try updating to a newer version.
