JSONDecodeError

[rgr7894]

I am getting a JSONDecodeError : Expecting value: line 1 column 1 (char 0) . CoreNLP and Grobid are running fine .
The code i have written is

import Measurements as m
import json

test = "The patient returned to Europe at 28 weeks of gestation."

coreNLP = "http://localhost:9000"
grobid = "http://localhost:8070/service"
patterns = "dependency_patterns.json"
write_to = "smaple_output.txt"

out = m.extract(test, coreNLP, grobid, patterns, write_to, show_graph=False, pretty=True)

Please help me out!
