Multi branch pipeline - build is failing while creating new branch or tag

[Anish Kuti]

Hi ,

I am using Jenkins ver. 2.176.2 and deployed in EC2 (Ubuntu) . I am using multi branch pipeline . The jenkins file is as below .  While I am creating a new branch or tag I was expecting to start a build.  But it is not happening . 

What I want that in creation of tags or branch (even if no change in tags/branch) , there need to be a build triggered automatically . Pls help 

In creation of new tag -  it is showing below and no build is triggering

No changes in any of the builds, or multiple SCMs in use.

In creation of new branch  -  it is showing below and build is falling
