ConfigService | Config Service is the server-component | Configuration Management library

I need to read JSON file and cast it to Java ArrayList, i have code:

I wanted to dynamically set the Websockets-gateway port from config in NestJS. Below is my websockets-gateway code.

I'm currently having a problem that i'm unable to solve. This is only in extreme cases, when the server, for some reason, goes offline, messages accumulate (100k or more) and then they need to be processed all at the same time. Even though i'm planning for this never to happen, i would like to have a backup plan for it and more control on this issue. I'm running an NestJS microservice against a RabbitMQ broker to get messages that arrive from IOT devices and insert them into a MySQL database. Every message has a little conversion/translation operation that needs to be done before the insert. This conversion is based on a single row query done against a table on the same SQL Server.

The order is the following:

• read message;
• select 1 row from database (table has few thousand rows);
• insert 1 row into the database;

Now, i'm facing this error:

I have what appears to be a common problem without a common solution. I am trying to access my .env data from my Nestjs app.module while importing Neo4jModule. If I use hardcoded values everything works fine but neither process.env or configService seems to get the values. I have seem many examples of this problem but apparently the answer is quite elusive. I have tried the following variations of answers but none works. I do understand that we are a bit early in the initialization process but I can't figure out how to delay the request until the initialization is complete.

I've got a app.config.ts file with plenty of config variables that look like this:

Sort of out of ideas here. I'm new to the Nestjs (or node backends in general) world and up until anything to di with the db, it's been a piece of cake.

I've turned synchronization off explicitly:

.env

I have this request that while hasProcessado == true performs 10 more requests and issues the last, if it fails 3 more requests are made.

But when I make the last request I need to notify the backend with a different header

My request:

On localhost all is good, but when I deploy the application to the server not working. If form request validation fails instead of bringing me back to the same page and showing an error, it redirects me to the index page.
