Same error for me when uploading a large CSV

clearing browser history and cookies fixed the issue for me.

I figure out how fix this problem. The problem appear when you are using a different domain from Heroku or other cloud service and you are masking it with your domain.

To solve this you can change App url or disable CORS and XSRF on Heroku. This last option is easy, just add this code on your

mkdir -p ~/.streamlit/
echo "\
headless = true\n\
port = $PORT\n\
enableCORS = false\n\
" > ~/.streamlit/config.toml

Please, think about the new risk you are opening up in you app if you disable CORS and XSRF.

Did someone fixed it on replit?

pip install streamlit==1.24.0 . Use this earlier version. It fixed the problem for me

We still face this issue with 1.24.1

I got it working on replit. Create a new folder called .streamlit and create a “config.toml” file inside it. Then add this to the file:

enableXsrfProtection = false
enableCORS = false

Saved me hours of debugging! I all ready had this enabled in a different environment and I only needed to apply it to a new one. Thank you very much!
