I want to save user as object in rating object, but when I am going to add it its userId adding instead of whole user object ?

everyone! I’m currently trying to set up my connection between front-end server(React app) with backend server(NodeJs). I tried making requests from frontend to backend using axios .I tested the backend requests on Postman and they work as expected. However,I can’t start my front-end server because I have this error
“Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

When I attempt to format the data being received from TableData I keep getting an error Cannot read properties of undefined (reading ‘replace’). This happens when I reload the page after trying to filter the data I have put a comment in the code to show the line that when i refresh and add the code it gives me the error.

I am new to React and Node.Js and I am trying to create a simulation site where a manager can upload promotions into the server to showcase. The images and pdf are able to be showcased on my own local machine but unfortunately , it doesn’t showcase on the real server. May I understand why this is happening and how I should fix this? My local machine is running on windows while the server is running on linux

When you log in and go to the main runs page, it should get the runs (JSON data type) from your account (in mysql database) and display them through a useEffect, but the useEffect does not seem to be running. Also when I try to add a new run, it adds it to the database but returns and error saying
TypeError: runs.map is not a function
at DisplayRuns

So, I am using react and node to build a website and when testing locally it worked fine ,but once i hosted it on VPS, it doesnt seem to be working. For example when I send a feedback from the feedback page, the feedback.json in the server is updated but on the admin panel, in feedback section the new feedback doesnot appear.
