Discord.JS module installation error in Heroku. How to fix?

Question

Node.js

I'm writing a JavaScript bot for Discord via Visual Studio Code . In this program, everything is fine, the installation of the modules was successful. I installed cheerio and request . Launched the bot in the program. But, there is a but. I use heroku for 24/7 work , there is no money for a normal hosting right now. In heroku, the node_models folder is not required. Even with it, the folder just goes to ignore, and this does not interfere with the work of the bot. As soon as cheerio and request appear in package.json , things change, it gives an error.

try adding the following key to package.json:

"engines": {
    "node": "ваша_версия_node"
 }

find out the version of node: node -vin the console.
recommended to use xin a patch to get the latest patch updates from Node.
you can also specify a minor range (for example, 14.15) and an exact version (for example, 14.15.4).

certainly not a solution, but there are other free hosting 24/7. For example something.host, try it
