TypeError: string

[KirtiMenon95]

Hi,

I am trying to use this action by writing below workflow
name: GitHub Advanced Security API to CSV

on:
push:
branches:
- main

jobs:
generate-report:
runs-on: ubuntu-latest

steps:
  - name: Checkout code
    uses: actions/checkout@v2
    
  - name: Run GitHub Advanced Security API to CSV action
    uses: advanced-security/ghas-to-csv@v3
    env:
      GITHUB_PAT: ${{ secrets.GHAS }}
    
  - name: Upload CSV
    uses: actions/upload-artifact@v3
    with:
      name: ghas-data
      path: ${{ github.workspace }}/*.csv
      if-no-files-found: error

when running the action I see error
Traceback (most recent call last):
File "/app/main.py", line 129, in
Starting GitHub security report...
code_scanning.write_repo_cs_list(cs_list)
File "/app/src/code_scanning.py", line 87, in write_repo_cs_list
if cs["state"] == "open":
~~^^^^^^^^^
TypeError: string indices must be integers, not 'str'

Please help me get this sorted.
