Go-pluginserver terminated when using custom Go plugin

Hello! I’m trying to use a custom Go plugin with my Kong, here are some details:

Kong Version: 2.0.2
Go Version: go version go1.13.5 linux/amd64
go-pluginserver version: Runtime Version: go1.13.5

I updated kong.conf to load my plugin, and Kong successfully starts. Although, when I execute a request to the service where my plugin is set, nothing happens, when I opend error.log i got a lot of this message:

And those last three lines go on forever:

2020/04/08 16:51:24 [notice] 27050#0: *19 [kong] go.lua:95 go-pluginserver terminated: exit 0, context: ngx.timer

Am I doing something wrong ? Any help would be appreciated.
