error is silent and ignored in cron

[mzy2240]

When scheduling a function using cron, it does not throw error or log anything if failed

module JuliaWebServer 
using Oxygen
using HTTP

@get "/greet" function(req::HTTP.Request)
    return "hello world!"
end

@cron "*/2" function error_msg()::Nothing
    throw("ERROR")
    return
end

serve()
end

I think this is the result of me not nesting the try catch deeply enough and the @async macro is silently handling the error:

ic. maybe this is helpful to address the issue? JuliaLang/julia#36854
