Cannot read property 'replace' of null, when running action

[SamVanhoutte]

Hello,

I am getting the following error, when running the action in Github workflow:

Run solidify/github-action-update-azapim@v0.9.5
  with:
    swaggerUrl: https://******-tst.azurewebsites.net/api/swagger.json
    creds: ***
check_suite_focus=true#step:2:5) 0-[7](https://github.com/CotacolHunting/cotacol-strava-workers/runs/5138815755?check_suite_focus=true#step:2:7) * * *
Parse Json
Get token
[object Object]
Error: Cannot read property 'replace' of null

I have linked to the Azure credentials that I already successfully used for other resources in the same group
So no idea what the reason could be?
