The command I’m running is:

./pact/bin/pact-provider-verifier \
--broker-username ${PACT_BROKER_USER} \
--broker-password ${PACT_BROKER_PASS} \
--provider-app-version ${GIT_COMMIT_PROVIDER} \
--provider-base-url ${APP_BASE_URL} \
--provider-version-tag ${CIRCLE_BRANCH} \
--pact-broker-base-url ${PACT_BROKER_BASE_URL} \
--provider ${PACT_PROVIDER} \
--consumer-version-tag main \
--wait 30 \
--verbose \
--publish-verification-results

And the verbose log output is:

Resolved, the

consumer-version-tag

should have been “master” not “main”. This is what happens when you have a branch naming strategy but don’t actually roll it across your estate 😂
