How do I make apiError as a string

Here's an example of how you can tell apart different errors:

import dropbox
from dropbox.exceptions import ApiError

dbx = dropbox.Dropbox("<ACCESS_TOKEN>")

try:
    print(dbx.sharing_create_shared_link_with_settings("/test222.txt"))
except ApiError as err:
    if err.error.is_shared_link_already_exists():
        print("Link already exists.")
    if err.error.is_path() and err.error.get_path().is_not_found():
        print("File not found.")
    elif err.error.is_settings_error():
        print(err.error.get_settings_error())
    else:
        print(err)
