Help Needed: Errors When Uploading PDF Files on Vercel Implementation

[Gusiion]

I implemented it on Vercel and it worked very well, the chat works and it can read images. However, when trying to upload other files, such as PDF files, the following errors appear: 'Failed to upload. Could not resolve host: supabase_kong_chatbotui' and 'Failed to process file. Reason: 404 Resource not found'. I followed all the settings suggested in the read-me, but the error persists and I can't solve it. If anyone can help me, I would be very grateful.
