Node.JS Issues writing to Google Cloud SQL but can read just fine

I have a Node API on a Droplet with a React Front End. When I spin up the environments locally the API read/writes just fine but when I deploy them on their respective Droplets, I can read data from the Node API but I can not write data.

The react Droplet can read and display the data from the API droplet but when it writes, the API sends a 200 response but no data is actually written.

When I investigate on the API Droplet server, I don’t notice anything in the error logs (Nginx) but apparently I am missing something.

Consider following scenario, please. Your API has got a bug, supposedly. You get an OK status (200) because data was successfully transferred from front-end app to back-end, without checking if it was actually written. So, I would start troubleshooting your issue on Google Cloud SQL side. I would check permissions for accessing SQL database.
