Loading data using pydgraph

Data is not getting loaded when using live loader. Encountering this error. I’ve separate files for Movies, Persons and Relationships (JSON format):

Movies – movie_id, title, revenue, budget, genres
Persons – person_id, person_name
Relationships – movie_id, RELATIONSHIP, person_id

I’m getting this error while trying to load Movies.json file. Zero and alpha are already running …

NOTE: I’ve not created any schema anywhere, since live loader automatically detects predicates, I wanted to do this
