Different types of branch.id and approvalRule.protectedBranchIds

[wrbbz]

What happened?

I am trying to get default branch of the project with:

const branchId = gitlab.getBranch({
  name: project.defaultBranch,
  project: project.pathWithNamespace,
}).then(branch => branch.id);

And after that to set it to projectApprovalRule:

const projectApproval = new gitlab.ProjectApprovalRule(`${repoName}-${ruleName}`, {
  approvalsRequired: 1,
  project: pulumi.all([project.id]).apply(([project]) => `${project}`),
  name: rule.name,
  userIds: rule.userIds,
  groupIds: rule.groupIds,
  protectedBranchIds: [branchId],
});

The problem is branchId has type string, while ProjectApprovalRule requires array of numbers.
The solution given in #28 does not work due to the fact that branchId looks like: project.pathWithNamespace: project.defaultBranch which could not be converted to number.

Expected Behavior

The expected behavior is an ability to pass an output of getBranch to ProjectApprovalRule creation

Steps to reproduce

It is enough to call getBranch method and pass the output to ProjectApprovalRule

Additional context

The GitLab API itself says that branch id has string type (URL-encoded name of the branch).

Nvm. Found out, what I am doing wrong.
There are protected branches and ordinary branches.
To get ids in numbers for protected branches, you have to call getProjectProtectedBranch and use its output
