yongboy opened a new issue #3423:
URL: https://github.com/apache/apisix/issues/3423
When I enable service discovery, eg `consul_kv.lua`, and export the string
type of port value by `_M.nodes(service_name)`,
then add `healthcheck` function for the service discovery within the
upstream object, when called`cecker:get_target_status`, I got the `nil, "target
not found"` response always, leading to the `healthcheck` does not affect
the invalid nodes at all :(
So, I should make some changes.
The `consul_kv.lua` old way:
```lua
local function parse_instance(instance)
......
return ip, port, instance.metadata
end
```
Now, I should return the `tonumber(port)` value as below:
```lua
local function parse_instance(instance)
......
return ip, tonumber(port), instance.metadata
end
```
:))
