Here is are the errors in the console:
POST http://localhost:3000/register net::ERR_EMPTY_RESPONSE
TypeError: Failed to fetch

I understand that "Failed to Fetch" is a Network error

So I checked the Network tab

I'm using Google Chrome and I thought the new default Referrer-Policy of strict-origin-when-cross-origin was the cause for the Network block. They added this around August 2020. As a potential solution, I added helmet to server.js and set the referrer-policy to the most permissive option: unsafe-url. I also added CORS to whitelist the two localhost ports.

My docker container is building fine, the changes I make on my local machine propagate to the container, the server in a Docker container is hosted on localhost:3000, the client is hosted on localhost:3001, I can access the PostgreSQL database in a Docker container via PSequel, the database tables are created as expected. I suspect the error is Network related and I suspect the solution will take place in server.js, but I must be missing something one or two layers deep.
