Request to '/pact' endpoint without body is failing making python-pact verification unusable

[Piotr Kopalko]

Request:
docker-compose run tests curl -X POST -H "X-Pact-Mock-Service: true" -H "Content-Length: 0" pact/pact

Response of pact-mock-service:

Please provide a git repository or docker-compose file that demonstrates the issue, as I cannot reproduce it locally. There must be something different about your environment.
