I have an application for resume shortlisting. since it has to take 100s of resume, this backend is not getting deployed on vercel which is showing “data is too long” as error. also pythonanywhere free version doesn’t helped out.
Now i am trying to deploy it on aws elastic beanstalk. It is given on flask production deployement documentation. i have used its documentation also step by step. i don’t have much idea of development and deployment. basically my tech stack is ML side.

this is in my terminal:
Creating application version archive “app-240711_173433735664”.
Uploading ats-backend/app-240711_173433735664.zip to S3. This may take a while.
Upload Complete.
