Syntax error on "=" NodeJs in Ubuntu 20.04 - node.js

Question

I have developed a NodeJs(v10.19.0) server on windows.
I now need to transfer it to a linux server running Ubuntu 20.04
When I try to start the server, I have a syntax error on a "=".
Here's the complet error:
/puppeteer/scraping-bot.js:6
static websiteRegex = /^(https?\:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})(\/[\w\W]*)*$/gm
^
SyntaxError: Unexpected token =

[nodemon] app crashed - waiting for file changes before starting...
Here's the code that outputs the error:
class ScrapingBot {
static websiteRegex = /^(https?\:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})(\/[\w\W]*)*$/gm
static phoneRegex = /\+?\d{1,4}?[-.\s]?\(?\d{1,3}?\)?[-.\s]?\d{1,4}[-.\s]?\d{1,4}[-.\s]?\d{1,9}/g;
static addressRegex = /(([a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ'.]*\s)\d*(\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']*)*,)*\d*(\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']*)+,\s([\d]{5})\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']+/
...
}
I set up Git with nano if that helps...
I have already tried to replace the "=".

As you can see in here, static class fields are not supported as of Node 10 ->
