Cannot create deployment variables

We cannot create deployment variables.

Reproduction steps:

• Go to Settings -> Deployment -> Staging
• Set variable name
• Set variable value
• Click add
• Notice how the variable appears for ~1s before disappearing

There is a 404 in the console for GET {{https://api.bitbucket.org/internal/repositories/imperocloud/impero_rs/deployments_config/environments/

/variables/?page=1&pagelen=100}}
