packit: Unable to push to remote fork 'fork' using branch 'rawhide' on src.stg.fedoraproject.org

I’m trying to continue work on the packit integration in the-new-hotness, but I found out I’m unable to push to my fork in the implementation I have.

Here is the minimal reproducer for the issue:

from packit.config import Config, PackageConfig
from packit.distgit import DistGit
from packit.utils import run_command


dist_git_url = "https://src.stg.fedoraproject.org/"
pagure_user_token = ****
fas_user = "zlopez"
raw_packit_config = {
    "authentication": {
        "pagure": {
            "token": pagure_user_token,
            "instance_url": dist_git_url,
        }
    }
}
config = Config(fas_user=fas_user, **raw_packit_config)

package_config = PackageConfig(
       downstream_package_name="0ad", dist_git_base_url=dist_git_url
)

dist_git = DistGit(config, package_config)

# Use master branch
branch = "rawhide"

dist_git.update_branch(branch)

cmd = ["rpmdev-bumpspec", "--new", "1.0", str(dist_git.absolute_specfile_path)]
run_command(cmd)

dist_git.commit("Test commit", "", prefix="[the-new-hotness]")
dist_git.push_to_fork(branch)

The token used for staging has following ACLs:

• Commit to a git repository via http(s)
• Fork a project
• Open a new pull-request

From what I tried to debug, the fork is created without issue.
