Hello @pgrzesik - I’m able to reproduce that issue on mac os 11.4 with very simple serverless.yml

service: testsls

provider:
  name: aws
  runtime: python3.8
  stage: dev
  region: us-east-1
  lambdaHashingVersion: 20201221


functions:
  hello:
    handler: handler.hello

This is my version of serverless:

sls --version
Framework Core: 2.51.0
Plugin: 5.4.3
SDK: 4.2.3
Components: 3.13.3

And here is the output of the command with debug:

sls deploy

As soon as the zip to be uploaded is bigger than 1mb, i’m facing that error. On version 2.49, it was exiting after the error, on 2.51 it’s getting stuck on that error message forever. I tried multiple version of node: same issue.

Sometimes i’m getting small variation of that error:

Serverless: Recoverable error occurred (TimeoutError: socket hang up
    at connResetException (internal/errors.js:628:14)
    at TLSSocket.socketOnEnd (_http_client.js:499:23)

But the behaviour is exactly the same, it’s getting stuck there.

I was also able to reproduce on a colleague mac running 11.4, same error as above.

Why is this closed? It’s clearly an open issue, and until there are clear instructions to people stuck on MacOS (even if they don’t require fixes to serverless.com framework itself) it should remain open. Many of your users will be in the same boat. Otherwise, update your supported versions and indicate clearly that serverless.com does not work with and does not support the latest MacOS versions.

We’re seeing this as an intermittent issue (which makes it a lot harder to debug) in Github Actions (so less likely to be speed)

Serverless version 3.34.0

OK thank you for the update, let’s close this for now then. If anyone is still stuck and has more details, let’s reopen!
