Cannot find module 'playwright-core'

Thank you for this library, I have found playwright to be superior to puppeteer and would prefer to use it on AWS.

Unfortunately currently I am getting an error whenever I try to use it, including the simple demo code in the README.

internal/modules/cjs/loader.js:638                                                        
    throw err;                                                                            
    ^

The offending line is: const playwright = require("playwright-core");

I’m developing on Windows but this happened on Lambda as well. I have npm install’d playwright-core, it definitely exists in node_modules
