Hello team!
I have a running app on streamlit and heroku with works with an .csv upload. So the upload works on local but not in the deploy (returns status code 403). Already tried updating the streamlit lib and changing the file but no results. Any help?


Hi @jgbalves,
Thanks for posting!
It looks like Heroku is blocking your attempt to upload a file – I would reach out to their support team for clarification.

Hello @Caroline!
All sorted, my url was masking Heroku, so the csrf was catching me
. Now it just redirects to the Heroku url. Thanks for the help!
