Hi , we have taken these https://github.com/pactflow/example-provider-springboot & https://github.com/pactflow/example-consumer-java-junit demo code and we have upgraded the Spring to 3.1.2 & Pact to 4.6.1. We are able to generate the contract and verify it from provider side using PactFolder but when we are trying to use PactBroker we are getting this error " Invalid JSON (1:4), found unexpected character 'm'. This blocking use to proceed further! if anyone has faced similar issues please show us some pointer !

au.com.dius.pact.core.support.json.JsonException: Invalid JSON (1:4), found unexpected character 'm'"
