WebSocket Router: defaultEnvTag

defaultEnvTag supplies the service-discovery environment tag when a selected pathPrefixService target does not define envTag.

• Type: String or null
• Default: unset

Blank values are normalized to unset. A target-level envTag overrides the default, and a non-blank env_tag or envTag query parameter overrides both. The resolved value is passed to registry discovery together with the service id and protocol.

defaultEnvTag: dev
pathPrefixService:
  /chat: com.networknt.chat-1.0.0
  /events:
    serviceId: com.networknt.events-1.0.0
    envTag: sit

In this example, /chat discovers the dev instance while /events discovers the sit instance.
