Have a look here,

Seems like triggering a Pipeline job from Freestyle job should be soon
possible.

In 'Build after other projects are built', did you specify a result option?

Well, I haven't found a solution, but I have found why the scheme we had 
stopped working.  Seems this error is being thrown whenever the first 
triggering build runs:

Triggering a multibranch pipeline build from a URL Change

[Greg Smith]

We would like to trigger a multibranch pipeline build whenever a file at a 
URL changes.  We had a mechanism that worked, but a recent update broke 
that mechanism.

Here's what we had setup:

URLTrigger used to trigger a Freestyle build, named "Stage1"
Pipeline build that runs whenever "Stage1" build completes, called "Stage2"
Pipeline build starts multibranch pipeline build in its script.

This Rube Goldberg like series of steps were required because a Freestyle 
build can not start a Pipeline build, but a Pipeline build can be triggered 
by a Freestyle build.  A multibranch pipeline build can not be triggered by 
a pipeline build, but a pipeline build can directly start a multibranch 
pipeline build.

At least, these used to be the rules.  We upgraded to the latest LTS 
release (2.46.1 -> 2.46.2) and the ability for a pipleline build to be 
triggered by the completion of a Freestyle build now seems to be gone.

I can configure the Pipeline build to run when the Freestyle build 
complete, but it never actually triggers.  

Ugh -- was hoping someone might know what the current rules are, or point 
me to a jira / bug.  I'm not even sure where to file such a problem report, 
as I'm not sure if this is core Jenkins function, or something to do with 
the pipeline plugins.

Has anyone got a multibranch pipeline build triggered by a URL change?  
Maybe I need to completely redesign this workflow.

Thanks much,
Greg
