When I create a project through the pipeline DSL plugin (code snippet below is for a multibranch pipeline) the credentials I created are not passed correctly through to Github and authentication fails.

Once I navigate to the newly created project and click "Configure" and then "Save" the configuration, Jenkins then scans Github successfully and everything works as expected.

I would like to spin up Jenkins completely through Chef and Groovy DSLs so that no manual intervention (like having to click "Save") is required.

Here is the DSL script I'm using:

UUID uuid = UUID.fromString("dd847135-8391-4f66-a54c-7f8781dc3119")
multibranchPipelineJob('test3') {
  displayName "test3"
  description "test3"
  branchSources {
    github

{       id(uuid.toString())        scanCredentialsId('gitusername_password')        repoOwner('my_user')        buildForkPRMerge(false)        repository("my-repo.git")     }

  }
}
queue("test3")

Here is the relevant portion of the logs:
