描述

When trying to use it with chrome headless instance, I'm getting:

Error: No inspectable targets
    at defaultTarget (/Project/node_modules/chrome-remote-interface/lib/chrome.js:45:23)
    at /Project/node_modules/chrome-remote-interface/lib/chrome.js:228:32
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:208:7)

Failing near here:

class Chrome extends EventEmitter {
    constructor(options, notifier) {
        super();
        // options
        const defaultTarget = function (targets) {
            // prefer type = 'page' inspectabe targets as they represents
            // browser tabs (fall back to the first instectable target
            // otherwise)
            let backup;
            let target = targets.find((target) => {
                if (target.webSocketDebuggerUrl) {
                    backup = backup || target;
                    return target.type === 'page';
                } else {
                    return false;
                }
            });
            target = target || backup;
            if (target) {
                return target;
            } else {
                throw new Error('No inspectable targets');
            }
        };

Running example with:

  const chromeless = new Chromeless({
    viewport: {
      width: 1440,
      height: 900,
      scale: 1,
    }
  });

  const screenshot = await chromeless
    .goto('https://www.google.com')
    .type('chromeless', 'input[name="q"]')
    .press(13)
    .wait('#resultStats')
    .screenshot();

  console.log(screenshot) // prints local file path or S3 url

    await chromeless.end()
