Invalid integration type for downloaded workspace credentials

When I downloaded my workspace credentials and attempted to add them to my project, I received an "Error: Missing or invalid keys in config" message. The issue was fixed by changing the integration_type from the default "oauthwebapp" to "oauthweb". The former isn't even in the "allowed values" list. Is this a known issue, or did I possibly do something wrong when setting up configuration for my workspace? 

Thanks!
