Headers and Body not being assigned to the ServerlessRequest in NodeJS v19.1.0

[RHJesse]

When making a request in NodeJS v19.1.0 the request headers and body don't get passed through correctly. After some debugging I've narrowed it down to this Object.assign in the request constructor: https://github.com/vendia/serverless-express/blob/mainline/src/request.js#L18

When making a request on Node v16.18.1 or v18.12.1 it's fine, but v19.1.0 it doesn't work, both the test header and all other headers aren't being assigned

16.18.1

18.12.1

19.1.0

Workaround is just to use NodeJS < 19 for now

the change causing this issue was reverted nodejs/node#45510 and released in v19.2.0

v20 will likely break again as this breaking change is being re-introduced.

Thanks for the heads up. We'll leave this open for tracking v20. Is there a recommended solution/workaround that will work for Node 14+?
