This is an issue regarding a bug in the Repository Settings
It says:
Use this deploy key with the Hatchbox Deploy GitHub Action.
[DEPLOY_KEY is here] [Copy/Paste button is here]
When you click the copy/paste button, it copies the following string:
https://app.hatchbox.io/webhooks/deployments/DEPLOY_KEY?latest=true
instead of copying the following string:
DEPLOY_KEY
