Which frappe version are you using?

I'm on version 12. But I think I figured out what was wrong. It was missing some check in the key_generator function regarding the docType. That is said I simplified this function as I just wanted my files to be uploaded at the root of my bucket so I ended up with this :

 def key_generator(self, file_name, parent_doctype, parent_name):
        """
        Generate keys for s3 objects uploaded with file name attached.
        """
        file_name = file_name.replace(' ', '_')
        file_name = self.strip_special_chars(file_name)
        key = ''.join(
            random.choice(
                string.ascii_uppercase + string.digits) for _ in range(8)
        )
       final_key = key + "_" + file_name
       return final_key
