Hi Team,
when I run the below code I get error , please help me to fix as I am testing a new project with Genie.

module App
using Genie
using Genie.Router
using Genie.Renderer
using Genie.Requests
using Genie.Renderer.Json
#using Genie.Requests.Params

include("add.jl")
using Genie.Renderer.Json
route("/add", method = POST) do
     data = jsonpayload()
     a = parse(Int, data["a"])
     b = parse(Int, data["b"])
     sum = add(a, b)
    return JSON(:result => sum)
end

end

Add function code

function add(a::Int, b::Int)
    return a + b
end

when I send a below curl request I get error

curl -X POST 'http://localhost:8000/add/' -H 'Content-Type: application/json' -d '{"a": "10","b": "28"}'

I’m not familiar with Genie’s exports, but

And

Have different case (Json vs JSON). Maybe try return Json(:result, => sum)?
