Serverless(Runpod) with "error": "'str' object has no attribute 'get'"

Kudos to the developer. It's an amazing serverless repo.

I've been using runpod serverless with a custom Docker image but now the worker generates images and save it to the storage but gives this error.

How can I solve it? Thanks in advance

It seems the issue comes from WAS Node suit (Image Save node) got an update and now it doesn't work with preview:true parameter.
