fallbackTag doesn't work and code throws NoPactsFoundException

[iankurrathi]

I am using 4.1.11 version of junit5 provider.

<dependency>
  <groupId>au.com.dius.pact.provider</groupId>
  <artifactId>junit5</artifactId>
  <version>4.1.11</version>
</dependency>

As per the documentation, I am specifying both tag and fallbackTag in my provider test class.

consumerVersionSelectors = {
                @VersionSelector(tag = "branch123", fallbackTag = "master")
        }

Now its supposed to use master tag contract if branch123 tag contract doesn't exist. However it doesn't work me and throws following error:

au.com.dius.pact.provider.junitsupport.loader.NoPactsFoundException: No Pact files were found to verify

I can confirm that master tag does exist from pact broker as well as using that in tag field and running the test successfully.

Looking at code of VersionSelector, it seems that does have fallbackTag() method, however when I go into PactBroker, consumerVersionSelectors() method doesn't seem to have any reference of fallbackTag:

https://github.com/pact-foundation/pact-jvm/blob/4_1_11/provider/src/main/java/au/com/dius/pact/provider/junitsupport/loader/VersionSelector.java

https://github.com/pact-foundation/pact-jvm/blob/4_1_11/provider/src/main/java/au/com/dius/pact/provider/junitsupport/loader/PactBroker.java

Thanks.

The fallback tag is passed on to the Pact broker. Can you provide debug level logs? It should show the request made to the Pact broker, as well as the response. Can you also confirm the version of your broker.

Pact broker version is 2.59.2.

Following are the debug level logs of provider:

Your broker does not support the new "pacts for verification" endpoint, that is why the fallback tag is not being used.
