V4: dev mode throws error when function invoked about serverless

[lorenwest]

The actual stack trace is a little different. Maybe this will help:

─ node:internal/modules/cjs/loader:1147
  throw err;
  ^

Same here

There is a conflict with dev mode in V4 and our observability product. We are working on a fix. ETA is ~1.5 days.

Fixed in https://github.com/serverless/serverless/releases/tag/v4.0.34

[lorenwest]

Just installed serverless v4 npm i -g serverless and am getting this same error. Performed a serverless update to get the latest 4.1.4

Does this require 4.0.34, or is the fix also in 4.1.4?

Thank you

@lorenwest Should be fixed. But if you saw this in 4.1.4 we better give it another look. @eahefnawy could you check this out pls?
