Playwright works locally but fails on CI

[Gbahdeyboh]

Context:

• Playwright Version: 0.13.0
• Operating System: Linux

Describe the bug

Playwright works normally locally, but when on the CI. The browser fails to Open. I get the error
TypeError: Cannot read property 'newContext' of undefined

The full log can be found here.

And I'm not exactly sure why this works locally and not on CI.

Hey @Gbahdeyboh,

I see there's the following line in the log:

browser = await Browser.startBrowser( 'chromium' );

which doesn't look like Playwright. Do you wrap it into something? Where can I get to look at the code?

[Gbahdeyboh]

Yes, I created a separate route to start the browser.

You can check the Browser class code here.

The whole code is here In case you need and other info from the code.

[Gbahdeyboh]

I stopped the use of the Browser class I wrapped around playwright to see if I was doing something wrong and I get a new kind of error here

(node:2725) ExperimentalWarning: The fs.promises API is experimental

Full error here

@Gbahdeyboh I'm sorry I didn't follow up on this. Is this still relevant?

[Gbahdeyboh]

No, not at all.
Just in case anyone else experiences the same issue, fs.promises(which playwright uses) is only stable in Node erbium(v12) upwards. I was also missing some Docker CI config, see here for correct configurations for your CI
