I am trying to deploy a project I created on Heroku and I have some trouble to do it... Anyone has any idea of what is going on ? It seems to do with sharp 'darwin-x64' but I really don't know what it is.

I'm trying to send a simple HTTP request to a ESP8266 from my Android phone. I'm following this tutorial. The code works for the URL used in the tutorial (https://reqres.in/api/users?page=2), however not for the URL that turns on the LED on ESP8266. (Turning on the LED is possible through a browser though, so it must be something with the code). The URL is https://192.168.137.78/led/1.
The stacktrace is quite long, but this is the first error,

I'm working on a Discord BOT using Node.js

I'm trying to get an image using a public API with no key needed, it's working locally but when I deploy it on Heroku, it doesn't work.

I need to know if Heroku is limiting the API requests and I should upgrade my "free" plan or I'm missing something.

Error message when trying to call the API :

Thank you for your help.

When you use Node to make an http/https request (or with a wrapper such as simple-get), you get back err, response, and data objects. Is there a way, within the callback, to get the original request URL, host, url, etc?

Example (using simple-get's concat):

Is there any way to synchronously execute a thread made with Lwt library?

To be specific, I am trying to run a series of post requests to a server that compute some value and returns a result.

Based on answers provided to this question:

How do I make a simple GET request in OCaml?

I can make it with either low level approach (sockets) or using the Cohttp library. The low level approach has the advantage of being immediate and straightforward but I would rather stick to the Cohttp (no need for read/write loop etc.). Unfortunately I am completely new to the Lwt and based on: https://mirage.io/wiki/tutorial-lwt I understand that the only way to get result from a t to a is to run Lwt_main.run which is suppose to be invoked at top level which is not an option for me.

TL:DR

Is there any way get a result from:

Client.get (Uri.of_string "http://localhost:8080/res")

without calling Lwt_main.run or is calling Lwt_main.run for each request (deep inside a code) not so bad idea ?

I have a problem installing the serial module on Node. I am using Raspbian server for orange pi zero H2.
