jenkins jobs failing after Github upgrade to 3.4.2

Question

Upgraded the GitHub enterprise server from version 2.22.5 to 3.4.2(latest). The github allows 2 jumps at a time during the upgrade.

Hence I upgraded from 2.22.5 to 3.1.7 and then from 3.1.7 to 3.3.7. Now the final upgrade from 3.3.7 to 3.4.2.

I tested the Jenkins jobs at each version and it worked but failed at the final version.

Here is the error description:

: ERROR : Received unexpected response with status code 404, when the expected status code was 200. Message: "{"message":"Not Found","documentation_url":"https://docs.github.com/enterprise/3.4/rest"}".
