API Error or Library Error, Specifying file type when creating block list draft create_block_list_draft

[rsinghrandhawa-ias]

I receive either an API Error when using the library for create_block_list_draft or an error in the code when trying to specify the file type

import logging
from facebook_business.api import FacebookAdsApi
from facebook_business.api import FacebookSession
from facebook_business.adobjects.business import Business

def main():
    BUSINESS_ID = "<obfuscated>"
    access_token = "<obfuscated>"
    app_secret = "<obfuscated>"
    config = {'app_id': BUSINESS_ID, 'app_secret': app_secret, 'access_token':access_token}
    session = FacebookSession(
        config['app_id'],
        config['app_secret'],
        config['access_token'],
        debug=True
    )
    FacebookAdsApi.set_default_api(FacebookAdsApi(session))
    fb_business = Business(fbid=BUSINESS_ID)
    filepath="testfile.csv"
    params = {
       'publisher_urls_file': filepath
    }
    response = fb_business.create_block_list_draft(params=params)
    print(response)

if __name__ == "__main__":
    logging.basicConfig(
        level=logging.INFO, format="%(levelname)s (%(name)s:%(lineno)s): %(message)s"
    )
    main()

I receive the following error

"message": "(#100) Param publisher_urls_file must be a file with one of the following types: text/csv, text/plain, application/vnd.ms-excel. Received file of type ''.",

So I tried a variation of that with

params = {
    'publisher_urls_file':(filepath, "text/csv")
}

And received an error in the library

response = fb_business.create_block_list_draft(params=params) File "/home/etl-pm-pipeline-facebook/venv/lib/python3.6/site-packages/facebook_business/adobjects/business.py", line 802, in create_block_list_draft request.add_params(params) File "/home/etl-pm-pipeline-facebook/venv/lib/python3.6/site-packages/facebook_business/api.py", line 656, in add_params self.add_param(key, params[key]) File "/home/etl-pm-pipeline-facebook/venv/lib/python3.6/site-packages/facebook_business/api.py", line 642, in add_param if not self._param_checker.is_valid_pair(key, value): File "/home/etl-pm-pipeline-facebook/venv/lib/python3.6/site-packages/facebook_business/typechecker.py", line 81, in is_valid_pair return self.is_type(value_type, value) File "/home/etl-pm-pipeline-facebook/venv/lib/python3.6/site-packages/facebook_business/typechecker.py", line 92, in is_type ... TypeError: stat: path should be string, bytes, os.PathLike or integer, not tuple

I also tried

in_file = open(filepath, "rb")
data = in_file.read() 
in_file.close()
params = {'publisher_urls_file': data}

and received this error compatible.
