I am trying to run a successful build on github, but CircleCI warns me that the key to github is read-only. What can I do?

The Github key is read-only, but cannot be changed, and it was created using circleCI:

My deploy_staging.sh:
#!/usr/bin/env bash
gulp
cd staging
git init
git checkout -b "staging"
git config user.name "circleci"
git config user.email "circleci@aaa.org.il"
git add . -A
git commit -m "build"
git remote add azure https://github.com/aaa/webogram.git
git push azure staging --force
Gulp creates a new directory - "staging" - and creates a project in it. Then I want to push the result to azure, so I try to use a new branch ("stage") and click on it only the assembly directory.
