Can't start reveal.js: Syntax Error: Unexpected token

Node version: v12.22.9

I'm installing reveal to Ubuntu. Having followed the steps described in Full Setup section of the docs, I'm running into the following error when trying to start with npm start -- --port=50788:

/etc/docker/compose/reveal/reveal.js/node_modules/glob/node_modules/minimatch/dist/commonjs/ast.js:86
    #fillNegs() {
             ^

SyntaxError: Unexpected token '('

I know little about JS, so I went and edited the implicated file by removing the hashtag sign from #fillNegs() { line, and got another error:

/etc/docker/compose/reveal/reveal.js/node_modules/glob/node_modules/minimatch/dist/commonjs/ast.js:140
                (this.#root.#filledNegs && this.#parent?.type === '!'))) {
                                                        ^

SyntaxError: Unexpected token '.'

So, clearly, manual editing is not the way. Perhaps, I'm missing some dependencies?
