I don't know what the purpose of the failed regex created in cr_buildtrigger_repo so I'll just show the (what I believe) to be standard use case for using googleCloudRunner::cr_buildtrigger with a GitHub repo. Making a cr_trigger_repo output with the source as the sourceToBuild as well as trigger:

repo_name = "StreamlineDataScience/targets-minimal"
github_secret = "ssh-deploy-key"

sourceToBuild = googleCloudRunner::cr_buildtrigger_repo(
  repo_name = repo_name,
  github_secret = github_secret,
  type = "github"
)
googleCloudRunner::cr_buildtrigger(
  build = "blah.yaml",
  name = "blah", 
  trigger = sourceToBuild,
  sourceToBuild = sourceToBuild)
#> Error: !grepl("[^A-Za-z0-9/.]", ref) is not TRUE

This drills down in different evaluations of the sub functions that are gone through before the error:

# inside cr_buildtrigger
if (!is.null(sourceToBuild)) {
  assertthat::assert_that(googleCloudRunner:::is.buildtrigger_repo(sourceToBuild))
  sourceToBuild <- googleCloudRunner:::as.gitRepoSource(sourceToBuild)
}
#> Error: !grepl("[^A-Za-z0-9/.]", ref) is not TRUE

# googleCloudRunner:::as.gitRepoSource
x = sourceToBuild
ref <- paste0("refs/heads/", x$repo$branchName)
ref
#> [1] "refs/heads/"

# 181
# GitRepoSource
!grepl("[^A-Za-z0-9/.]", ref) # regex not allowed
#> [1] TRUE

I don't know why this is excluded in your code as I don't see anything related to this and the docs don't indicate this: https://cloud.google.com/build/docs/api/reference/rest/v1/projects.locations.triggers#BuildTrigger.GitRepoSource
