Comment 1 for bug 1528595

Had this bug occur in a recent env during a separate task, so took the oppertunity to debug, finally tracked it down to the config_path env, which is evaluated lazily as part of the checks.0.command in the nrpe call, it needs to be fixed to not rely explicitly on the relation data:

config_path: "{{ relations['conn-check'.0|default({})['config_path'] | default('/srv/conn-check/config.yaml') }}"
