I think I found a small bug with using

S3PutObject

in

put_files()

s3.py:1322     isinstance(key_path, tuple)

is true when key_path is an S3PutObject. Here is my fix.

for key_path in key_paths:
    if isinstance(key_path, S3PutObject):
       key = key_path.key
       path = key_path.path
    else:
       key = key_path[0]
       path = key_path[1]

interesting, thanks! @dry-beach-38304 can you take a look

I'm running in python 3.11.7
