JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[shreyanarula3 (Shreya Narula)]

I am getting this error on executing this:
descriptions = None
with open(“descriptions_1.txt”,‘r’) as f:
descriptions= f.read()

json_acceptable_string = descriptions.replace("’",""")
descriptions = json.loads(json_acceptable_string)
