TypeError: object of type 'NoneType' has no len()

[learnerboy88]

I am getting the error when running this command
arjun -i burpRequests -m JSON --headers "Authorization: Basic exampleheaderrunninghere" -oT arjun-result --include='{"root":{"a":"b",$arjun$}}'

Error:

Traceback (most recent call last):
  File "/home/kali/.local/bin/arjun", line 8, in <module>
    sys.exit(main())
