Docker – Unreachable code when connecting to mongoDB

I am trying to dockerize my node.js app and it just won’t work. I narrowed the point of error down to two lines, but I just can’t get to the ground of the problem. I’ll share my code if you need more just ask for it. I am using a raspberry pi 3 to deploy my container unsing portainer. Maybe I missed a setting there idk.

console.log("Hello from the docker3")

//Database
const mongoose = require("mongoose");

mongoose.connect(
  `mongodb+srv://{process.env.DB_USER}:${process.env.DB_PASSWORD}@${process.env.DB_ADDRESS}/`
);
console.log("Hello from the docker4")

The rest of the code are just some webpages that get sent and some express.js stuff.

My error

I am getting this error from this part, you can see that the print number 4 doesn’t get printed so I think it’s somewhere there

I searched everywhere but I couldn’t find a reason for this.

    Can you modify your connection code to log any errors that occur during the connection process. This can provide more insight into what’s happening :

    const mongoose = require("mongoose");
console.log("Hello from the docker3");

mongoose.connect(
  `mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASSWORD}@${process.env.DB_ADDRESS}/`,
  { useNewUrlParser: true, useUnifiedTopology: true }
).then(() => {
  console.log("Connected to MongoDB successfully");
}).catch((error) => {
  console.error("Error connecting to MongoDB:", error);
});

    mangoose return promise object and if we want to get response from promise object either we have to use await or then Try following ways

    try {
    await mongoose.connect(
        mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASSWORD}@${process.env.DB_ADDRESS}/
    );
    console.log("Connected to MongoDB");
} catch (error) {
    console.error("Failed to connect to MongoDB:", error);
}

    Ensure that the environment variables (DB_USER, DB_PASSWORD, DB_ADDRESS) are set correctly. You can print these values to the console to verify if they are being correctly retrieved from the environment:

    console.log("DB_USER:", process.env.DB_USER);
console.log("DB_PASSWORD:", process.env.DB_PASSWORD);
console.log("DB_ADDRESS:", process.env.DB_ADDRESS);
