Getting "TypeError: unsupported operand type(s) for -: 'dict' and 'int'"

I must overlook something here so sorry for the basic question here!

after installing es2csv I tried to run it against public ES cluster
es2csv --verify-certs -u https://myes.com -i logstash-* -D log -q 'spot' -o database.csv

I get

Found {u'relation': u'eq', u'value': 250} results.
Traceback (most recent call last):

TypeError: unsupported operand type(s) for -: 'dict' and 'int'

Not sure what I need to add to avoid the cast issue.

Line 127 in es2csv.py is the cause of the issue and it is because the result set has changed in ElasticSearch 7.0.

self.num_results = res['hits']['total']

returns a dict rather than the number expected. Changing line 127 to the following fixes the issue

self.num_results = res['hits']['total']['value']

This is caused by a breaking change in ElasticSearch 7.0 where hits are now returned as an object.
