Question

I am getting error running below in jinja.

raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

"fc_key": {{ '"'+metadata['config_group']|string+'"' if metadata['config_group'] is not none else '""' }}, "fc_value": {{ inputs['data'] | replace("'", '"')}}

raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) .

Can someone please help
