I have done some digging and there seems to be a problem with *to_nice_json* .
if I use -{{ hostvars | *to_nice_json* }} it breaks if I use -{{ hostvars | *to_json* }} It works correctly def to_json(a, *args, **kw): ''' Convert the value to JSON ''' return json.dumps(a, *args, **kw) def to_nice_json(a, *args, **kw): '''Make verbose, human readable JSON''' return json.dumps(a, indent=4, sort_keys=True, *args, **kw) It does look like it uses a different encoder under the hood if indent & sorting is enabled https://sourcegraph.com/hg.python.org/cpython@default/.PipPackage/Python/.def/json/dumps/cls?_codeview=1 # cached encoder if (not skipkeys and ensure_ascii and check_circular and allow_nan and cls is None and indent is None and separators is None and default is None and not sort_keys and not kw): return _default_encoder.encode(obj) if cls is None: cls = JSONEncoder return cls( skipkeys=skipkeys, ensure_ascii=ensure_ascii, check_circular=check_circular, allow_nan=allow_nan, indent=indent, separators=separators, default=default, sort_keys=sort_keys, **kw).encode(obj) -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
