Python Office365 Rest API - Error with get_folder_by_server_relative_url .add function

Question

I have had a script that worked fine for as long as I can remember, however, recently it has errored out with the below:

TypeError   Traceback (most recent call last)
Cell In[19], line 53
     50 info.url = target_file
     51 info.overwrite = True
---> 53 result_file = context.web.get_folder_by_server_relative_url(target_folder).files.add(info)
     54 context.execute_query()
     55 print('File {0} has been uploaded successfully'.format(result_file.properties['ServerRelativeUrl']))

TypeError: add() missing 1 required positional argument: 'content'

I cannot figure out how to resolve this or which positional argument might be missing. Any help is highly appreciated as I have been trying to figure this out all day to no avail :(

You are reading the file content and setting it in the info.content property but, it the library wants you to pass the content as a parameter to the add method

result_file = context.web.get_folder_by_server_relative_url(target_folder).files.add(target_file, file_content, True)
