cli/init.go:42 failed to initialize terrascan. error : failed to download policies. error: 'repository already exists'

[zoezhangmattr]

we are using pre-commit, with terrascan
pre-commit version 4.1.0
terrascan version 1.19.9
terraform version 1.11.1

pre-commit config

repos:
- repo: https://github.com/antonbabenko/pre-commit-terraform
    rev: v1.97.4
    hooks:
    - id: terrascan
      args:
          - >
            --args=--severity High --non-recursive

when running precommit in github workflow.
we dont specify any terrascan extra configs. or policy configs.
the error occurs
cli/init.go:42 failed to initialize terrascan. error : failed to download policies. error: 'repository already exists'

what i tried,
remove ~/.terrascan folder (even though nothing is there) just make sure there is no such folder in the github runner.
ls -all ~/.terrascan || true
ls -all ~/.config/terrascan || true
ls -all /tmp/terrascan || true
rm -rf ~/.terrascan
rm -rf ~/.config/terrascan
rm -rf /tmp/terrascan
ls: cannot access '/home/runner/.terrascan': No such file or directory
ls: cannot access '/home/runner/.config/terrascan': No such file or directory
ls: cannot access '/tmp/terrascan': No such file or directory

nothing works

i enabled debug logs, found something weird,

it tried to download policy twice? could this be the cause for repository already exist.

also absolute rego_subdir path, /opt/actions-runner/_work/my-repo/my-repo/terraform/oidc/pkg/policies/opa/rego, does not fall under base repo path's /home/runner/.terrascan directory structure
we dont have any policy config under the repo. folder terraform/oidc, why it will show this?
