Build parameters are not updated into Jenkins job

Hi Team,
Please find the issue details below
Jenkins : 2.319.3
Source code Ref: Github
Job configuration: Job DSL groovy script

I am using Job DSL to configure the Jenkins pipeline jobs. When I am trying to update the choice parameters details using groovy script, all the changes are reflected into Jenkins pipeline build parameters configuration but when I am trying to build the pipeline using build parameters all values are coming null.

How do you get them out?
