Error: Unknown object type "asyncfunction"

Question

I have and issue with my serverless deployment to AWS. Im fairly new to it so I'm unsure as to what the issue is.

I have found a few solutions online but none have worked so any ideas would be greatly accepted. also I know there is a very similar question on here but that solution didnt work and after asking for more details nobody responded so I made a new question. Please help!

The issue is happening with node version v15.8.0. Resolved by downgrading system version to v14.15.5 using nvm

Problem was 'object-hash' in Node modules

Remove the object hash references throughout the service (Use Find tool)

Had to comment out part of the code in the handlers

Remove the node modules folder altogether then

Then run yarn install to remove the object-hash dependency

Make sure it is uninstalled by using the find tool

Run sls deploy again

Asynync Error should be gone then....

If THEN run into a failed Uploaded file must be a non-empty zip

There is a problem with node version

Reduce to node version 14.15.1 here using homebrew (Mac)

Solved the issue for me!
