Serverless-webpack: Directory names that start with a dot are not being included in the zip file

Bug

Description

After upgrading from 5.3.5 to 5.4.0 I started getting the error below, I noticed that archived was replaced by bestzip and this is exactly what is failing, not sure what is causing this issue but I use hidden folders (starting with dot) for auto generated code that is packaged by serverless and bestzip may not be able to find the folder.

• What stacktrace or error message from your provider did you see?

zip error: Nothing to do! (../onAppInstanceSyncStorage.zip)

I'm sorry about that error.
Is there any chance you can provide a simple project to reproduce the error? So we can track it down and update serverless-webpack or bestzip to fix the issue.
Thanks

let me try, my setup is pretty complex

Same question then: Is there any chance you can provide a simple project to reproduce the error?

@christiantakle thanks for the repo, it helped me a lot.
In fact, when we zip files, we use * to match all files. But, according to the doc, it does not include dotfiles by default.

I managed to fix it by providing a list of files to the zip command and then found the fix was already provided in an other PR: https://github.com/serverless-heaven/serverless-webpack/pull/777
