I try to upload in production I get an error: An internal server error occurred

Hi,
I deployed Strapi to Heroku with Cloudinary and MongoDB Atlas and it’s working perfectly in localhost, however when I try to upload to production I get an error: An internal server error occurred.
If I try to upload to localhost it works fine and the image is available in production, but I can’t delete or upload another in production.

what did I do wrong?

Thank you all
