Environment variables aren't injected properly for specific branch deploys #6891
Description
Describe the bug
When using a specific branch context for running netlify build or netlify deploy, no environment variables are being injected. This is because the API call for getting the correct branch specific environment variables is failing. The context that's provided, isn't allowed as the API returns the following error message:
{
"code": 400,
"message": "invalid request: non-compatible context"
}
Steps to reproduce
- Create a new Netlify site
- Add a environment variable (i.e.
FOO=BAR) - Add a new branch, like
testand use a unique value for the environment variable (i.e.FOO=HELLO) - Add a
console.logwithin your application so that the environment variable is visible when runningnetlify build(i.e.console.log(process.env.FOO)) - Run
netlify buildfor the specific branch (i.e.netlify build --context="branch:test) - See that the log shows
undefined - Run
netlify buildfor the genericbranch-deploycontext:netlify build --context="branch-deploy - See that the logs are showing the correct environment variable
CLI command and flags
netlify build --context="branch:test"
