I encountered the same issue. The problem appears to be that the user agent is not defined in Node.js. I used JSDOM to create a workaround that solved the issue for me:

Important: You must call require("echarts") after defining the JSDOM props.

I only need server-rendered SVG images, not canvas images. An empty createCanvas is sufficient for my needs. However, if you are using canvas, you may need to use node-canvas.

const { JSDOM } = require("jsdom");

const { window } = new JSDOM();
global.window = window;
global.document = window.document;
global.navigator = window.navigator;
global.navigator.userAgent = window.navigator.userAgent;
global.navigator.language = window.navigator.language;

const echarts = require("echarts");

echarts.setPlatformAPI({
  createCanvas() {},
});

In node 21.1.0 navigator has now userAgent. Is your issue now solved?

I tried using node v21.1.0: the error is still present but different.

[...]\node_modules\.pnpm\echarts@5.4.3\node_modules\echarts\dist\echarts.js:123
        env.touchEventsSupported = 'ontouchstart' in window && !browser.ie && !browser.edge;
                                                     ^

Node.js v21.1.0

[...] = my project folder

I tried also to apply the solution proposed by @mahdi-shojaee, adding jsdom before echarts import

import { JSDOM } from 'jsdom'

const { window } = new JSDOM();
global.window = window;
global.document = window.document;

import * as echarts from 'echarts'

The error is still present, but different:

[...]\node_modules\.pnpm\echarts@5.4.3\node_modules\echarts\dist\echarts.js:16598
      document.documentElement.lang || navigator.language || navigator.browserLanguage).toUpperCase();

Node.js v21.1.0

[mahdi-shojaee]

@DarioMagniPLRM, You didn't add the navigator and its userAgent and language properties.

[Uzlopak]

I added a PR language and expect that it lands the next days.

Also I guess the nodejs detection is not implemented like usual.
