如何使用gitlab-ci.yml更新gitlab中JSON文件的内容？

stages:
  - update_json

update_json:
  stage: update_json
  script:
    - export JSON_CONTENT=$(curl -s --header "PRIVATE-TOKEN: $CI_JOB_TOKEN" "https://gitlab.example.com/api/v4/projects/$CI_PROJECT_ID/repository/files/path/to/json/file/raw?ref=$CI_COMMIT_REF_NAME")
    - echo $JSON_CONTENT | python3 -c "import json, sys; data = json.load(sys.stdin); data['key'] = 'new_value'; print(json.dumps(data))"
    - export UPDATED_JSON_CONTENT=$(echo $JSON_CONTENT | python3 -c "import json, sys; data = json.load(sys.stdin); data['key'] = 'new_value'; print(json.dumps(data))")
    - curl --request PUT --header "PRIVATE-TOKEN: $CI_JOB_TOKEN" --header "Content-Type: application/json" --data "$UPDATED_JSON_CONTENT" "https://gitlab.example.com/api/v4/projects/$CI_PROJECT_ID/repository/files/path/to/json/file?branch=$CI_COMMIT_REF_NAME&commit_message=Update%20JSON%20file%20via%20CI%2FCD"
