Scheduled pipeline failing with "404 Project Not Found" with CI_JOB_TOKEN

I have a scheduled pipeline that was working fine before (IIRC) and fetches a file from the package registry.

To fetch the file from the latest version of the package I'm using CI_JOB_TOKEN, but the job is now failing with 404 Project Not Found error

The following command is in the before_script (I'm using it to fetch the latest package id and using the id then to fetch the file):

curl -s \
     --header "JOB-TOKEN: $CI_JOB_TOKEN" \
     "${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/"
{"message":"404 Project Not Found"}
