stmts_from_json_file not working

@bgyori I'm getting the following error while trying to import statements from the output statements JSON file using the stmts_from_json_file function. Is this the right function to use?

>>> from indra.statements.io import stmts_from_json_file
>>> stmts = stmts_from_json_file("indra_statements_format.json")
ERROR: [2019-06-11 09:45:02] indra.statements.concept - Concept missing name.
