Bug - API v3 - HTTP 409 when setting environment variable even though it does not exist

curl --fail -X POST \
  -H "Content-Type: application/json" \
  -H "Travis-API-Version: 3" \
  -H "Authorization: token ****************" \
  -d '{"env_var.name":"SSH_KEY_NODE_INSTANCE","env_var.value":"test123","env_var.branch":"aeuohueotueueost","env_var.public":true}' \ 
  https://api.travis-ci.com/repo/******/env_vars

curl: (22) The requested URL returned error: 409 

I get the above http 409 response when trying to create an env var… This seems to be a bug. If I try ANY rando string for the branch_name I get the same result.

Still waiting on a response from this from support since yesterday…
