We have a multi job configured in our system and the delivery pipeline view when opened gets timed out. Can't see any error in Jenkins log as such. Referred to similar issues but they did not seem to help me.
Our multi job is formed of multiple multi jobs which are parameterized and it has promotions added to it.
Attached is the error screenshot.
Jenkins version: 1.651.1
Delivery Pipeline Plug-in version: 0.9.12
