Getting some errors after I've wrapped my Playwright project in a Docker image. I'm using Firefox in Playwright.
Dockerfile
FROM mcr.microsoft.com/playwright:next
WORKDIR /app
COPY package.json package-lock.json ./
RUN npm ci
COPY . .
RUN npx playwright install
CMD ["node","index.js"]
Package.json dependencies
"@extra/humanize": "^4.2.2-next.616",
"playwright": "^1.15.0",
"playwright-extra": "^4.2.1-next.616"
index.js
const { firefox } = require('playwright');
(async () => {
const browser = await firefox.launch();
const page = await browser.newPage();
await page.goto('http://whatsmyuseragent.org/');
await page.screenshot({ path: `example.png` });
await browser.close();
})();
It builds fine, but when I'm running it I'm getting this error:
browserType.launch: Protocol error (Browser.enable): Browser closed.

UPDATE:
If anyone is having the same issue, I found out that the Docker image is not valid on MacBook M1 (which I'm running) sadly :(
CodePudding user response:
As you have already stated, this is a bug (which is now in a feature request), since the docker file given by MS Devs fails for the M1 Macs.
Here is the link to the feature request - https://github.com/microsoft/playwright/issues/7723
