I saw this issue was earlier raised by another team https://github.com/pact-foundation/pact-jvm/issues/1265. And the issue is still open. Can you help us fix this issue ASAP.

Failed to invoke provider method 'verifyMessageforOrder'

means that the Pact framework tried to call your function and an exception was raised. A lot of the time it is because something is not correct in the function being called (like using a null variable). You need to look at your log output (set at debug level), and then look at the cause of the exception.

Thanks ... found the root cause of this issue. Pact Provider Contract Test was expecting both Test Class as well as provider method to use public access specifier.
