failed to set upstream: discovery eureka is uninitialized

Question

I am trying to connect apisix with the eureka discovery service. But I am getting this error.

error [error] 49#49: *913 [lua] init.lua:551: handle_upstream(): failed to set upstream: discovery eureka is uninitialized, client: 112.134.1.155, server: _, request: "GET /api/v1/decodeToken HTTP/1.1", host: "52.53.116.106:9080"

The configured config.yaml file is as follows:

apisix:
  node_listen: 9080              # APISIX listening port
  enable_ipv6: false

  enable_control: true
  control:
    ip: "0.0.0.0"
    port: 9092
  discovery:                       # service discovery center
      eureka:
