Problem with deploying a flask app with RAG to vercel

Question

i am trying to push my rag app to vercel but when i visit the site, i receive a 404. the app is built with the following components:

• flask for the frontend
• vanilla js for rendering content to the front end
• python for the RAG back end
• chroma as the vector db
• gpt-4 LLM and langchain for RAG integration

i am using conda as my dependency manager. below is my file structure:

C:.
|   .env
|   .gitattributes
|   .gitignore
|   app.py
|   client_secrets.json
|   config.py
|   environment.yml
|   functions.py
|   image_embedding_system.py
|   image_retrieval_system.py
|   LICENSE.txt
|   environment.yml
|   README.md
|   vercel.json
|   
+---.vercel
|       project.json
|       README.txt
|            
+---db
|   |   chroma.sqlite3
|           
+---instance
|       users.db
|       
+---models
|       model.pkl
|       
+---scripts
|       imports.sh
|       pusher.sh
|       remover.sh
|       
+---static
|                   
+---templates
|       index.html
|      
|   \---profile
|           edit_profile.html
|           profile.html
|           setup_profile.html
|           

i committed changes to my github repo, connected it to vercel, and made a deployment. i therafter expected to see the site live. i received 0 warnings and errors in the vercel gui, thus i'm unsure of what could be wrong. i dont suspect it could be the fact that vercel supports pip as the primary dependency manager, otherwise a build error would have been be logged.
