Github Actions environment variables not being set on Linux - github

Question

I'm trying to set my Github secrets as env variables via Actions but for some reasons they aren't being set (Using Ubuntu 22.04.1 LTS).
name: My app
on:
push:
branches: [ "main" ]
env:
JWT_SECRET_KEY: ${{ secrets.JWT_SECRET_KEY }}
JWT_REFRESH_SECRET: ${{ secrets.JWT_REFRESH_SECRET }}
MONGO_CONNECTION_STRING: ${{ secrets.MONGO_CONNECTION_STRING }}
PLAI_APP_URL: ${{ secrets.APP_URL }}
SENDGRID_API_KEY: ${{ secrets.SENDGRID_API_KEY }}
permissions:
contents: read
jobs:
build:
runs-on: self-hosted
steps:
- name: check out latest repo
uses: actions/checkout#v3
with:
ref: main
- name: Set up Python 3.10
uses: actions/setup-python#v3
with:
python-version: "3.10"
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r requirements.txt
Workflow runs successfully without errors but when I check my variables via env they are not listed. Any idea what I'm doing wrong?

You could follow the same idea as in "Managing secrets in an open-sourced flutter web app" from Mahesh Jamdade:
encode your confidential file to base64 and store the encoded output to GitHub secrets.
In your GitHub workflow decode the encrypted secret and convert it back to a file and then run your build scripts.
You can see an example in "How to access secrets when using flutter web with github actions".
