Error with python-index token with azure

[fensoft]

Hi,

I've put this as a dependabot.yml:

version: 2

registries:
  bcp:
    type: python-index
    url: https://pkgs.dev.azure.com/.../pypi/simple/
    token: <token>

updates:
- package-ecosystem: pip
  directory: "/"
  registries:
    - bcp

While doing this:
dependabot update --local . --provider azure pip <repo>

I got a 403 error on fetching https://pkgs.dev.azure.com/.../pypi/simple/<package>/

But I got the content while doing this:
curl https://pkgs.dev.azure.com/.../pypi/simple/<package>/ -H 'Authorization: Bearer <token>' -X GET

What have I done wrong ?
