Why no PACT is returned when calling path /pacts/provider/<name>/for-verification

I have a strange issue, I am creating a 2nd pact for consumer A, the first provider is B, and now I just uploaded the pact for provider C. The issue is that although I see the pact on the UI, when the curling/calling.

Using:

pact for junit5 4.6.3

pact-broker 2.110.0-pactbroker2.107.1

https://brokerurl/pacts/provider/C/for-verification

I see this

{"_embedded":{"pacts":[]},"_links":{"self":{"href":"https://brokerurl/pacts/provider/C/for-verification","title":"Pacts to be verified"}}}

I dont know what the issue is as I upload the contract from the same class in the consumer side.

Any ideas?

    }
}

I also tried use a random name for the new service C like (test-provider) and I get the same error, so I am wondering if the issue is the name of the expectation. Please any help is welcome.

So I found that the query for the latest pact searchs for main branch on the pact_publications "branch_heads"."branch_name" AS "branch_name".

Here is the full query:

SELECT "pact_publications".* FROM (SELECT "pact_publications".*, "branch_heads"."branch_name" AS "branch_name" FROM "pact_publications" INNER JOIN "pacticipants" AS "consumers" ON ("pact_publications"."consumer_id" = "consumers"."id") 
INNER JOIN "branch_heads" ON (("pact_publications"."consumer_version_id" = "branch_heads"."version_id")
# The issue was on this inner join on the second conditional
AND ("consumers"."main_branch" = "branch_heads"."branch_name")) WHERE (("pact_publications"."provider_id" = 15) AND ("pact_publications"."consumer_id" IN (SELECT "pacticipants"."id" FROM "pacticipants" WHERE (("name" = 'resolve-core-ticket-service-async') AND ("pacticipants"."id" IS NOT NULL)))))) AS "pact_publications" INNER JOIN "latest_pact_publication_ids_for_consumer_versions" AS "lp" ON ("lp"."pact_publication_id" = "pact_publications"."id")

Long story short, if you dont tag it with main, it won’t return it. This break a bit the flow we thought for onboarding an application but we found a workaround.

Also if you main branch is master you might need to update your CI or run a command to update the main branch of a pacticipant.
