How to run same job with different parameters in parallel using parallel[:] step - jenkins

Question

I have a pipeline script that needs to trigger a "TEST" job.
The main parameter (string) is SETUP_DESCRIPTION which I phrase from a json file I'm creating.
Each server can have different amount of outputs depends on server resources (some have 2 setups and some 3).
Code looks like this:
#!/usr/bin/env groovy
import hudson.model.Result
import hudson.model.Run
import groovy.json.JsonSlurperClassic
import jenkins.model.CauseOfInterruption.UserInterruption
import org.jenkinsci.plugins.workflow.steps.FlowInterruptedException

1) When I run it like code above build_sanity function called once and execute (instead of 3 times as expected).
2) When I take build_sanity function content and run it inside the ech loop in the tests stage it runs 3 times as expected but not choosing different parameters as expected.

Answer 1

so i managed to figure it out.
1) i have println some parameters and saw my function did not received the variables ok
so i have changed the build job: part and that fixed that issue.
2) i also had issue in the stage part. i put the "run parallel" inside the each loop which cause it to ran several times. so i drop it one } down and that fixed the loop issue
here is the function code + stage if anyone encounter such issue in the future
