I'm not sure where is the problem. The .env file is:
API_KEY=uAo5555JrIwhatever
LIBRARY_ID=666
COLLECTION_NAME=Remarkable
FOLDER_NAME=Zotero
STORAGE_BASE_PATH=
Any ideas?

The script is able to obtain the collection_id
Out[5]: 'A5ZJV3Q6'
So, there is connection, and even the collection is accesible, but then:
getPapersTitleAndPathsFromZoteroCollection(zotero, collection_id, STORAGE_BASE_PATH)
Out[7]: []
And there is two pdfs at the collection.
Thansks.
