Looking at this now.

[heitorlessa]

it's a regression not caught by tests - we're making a fix and a patch release now

[heitorlessa]

2.39.0 release yanked, merged regression fix, and we're starting a patch release now.

[heitorlessa]

@wurstnase 2.39.1 is now live in PyPi; we're testing locally with a new project to be sure too. Lambda Layers are starting now

Edit: @leandrodamascena just tested in a new project and worked. Let us know otherwise please.
