Workflows run Dataform repo that connected to Github

[sysph]

Hi all,
I wonder if any can help?
I've connected Dataform repo to Github repo and I've also triggered via Workflows by referencing this doc. https://cloud.google.com/dataform/docs/schedule-executions-workflows
Here's the source code in Workflows:

main:
    steps:
    - init:
        assign:
          - repository: projects/<gcp_project_name>/locations/<dataform_repo_location>/repositories/<dataform_default_repo_name>
    - createCompilationResult:
        try:
            call: http.post
            args:
                url: ${"https://dataform.googleapis.com/v1beta1/" + repository + "/compilationResults"}
                auth:
                    type: OAuth2
                body:
                    gitCommitish: main
            result: compilationResult
        except:
            as: e
            steps:
                - known_errors:
                    switch:
                    - condition: ${not("HttpError" in e.tags)}
                      return: "Connection problem."
                    - condition: ${e.code == 404}
                      return: "Sorry, URL wasn't found."
                    - condition: ${e.code == 403}
                      return: "Authentication error."
                - unhandled_exception:
                    raise: ${e}
    - createWorkflowInvocation:
        try:
            call: http.post
            args:
                url: ${"https://dataform.googleapis.com/v1beta1/" + repository + "/workflowInvocations"}
                auth:
                    type: OAuth2
                body:
                    compilationResult: ${compilationResult.body.name}
                    invocationConfig: 
                        fullyRefreshIncrementalTablesEnabled: false
                        includedTags: ["ga4"]
                        includedTargets: []
                        transitiveDependenciesIncluded: true
                        transitiveDependentsIncluded: false
            result: workflowInvocation
        except:
            as: e_execute
            steps:
                - known_errors_execute:
                    switch:
                    - condition: ${not("HttpError" in e_execute.tags)}
                      return: "Connection problem."
                    - condition: ${e_execute.code == 404}
                      return: "Sorry, URL wasn't found."
                    - condition: ${e_execute.code == 403}
                      return: "Authentication error."
                - unhandled_exception_execute:
                    raise: ${e_execute}
    - complete:
        return: ${workflowInvocation.body.name + " complete"}

Before i connected Dataform repo to GitHub repo, I used the default Dataform repository and everything works well.  However, i got this error message in Workflows after i connected to GitHub.

I've pushed changes to github repo and with default branch "main".  (Dataform repo name is different from Github repo name. Not sure if it's matter?) I'm appologised that i can't share the github repo.  

I thought maybe i need to configure NPM package? After i configured NPM package, i got different error in Workflows. Anyone had the same issue before? Thanks in advance.
