The Deno.exit() function is not available on Deno Deploy. It doesn't really make sense in a serverless platform where you spin a function up and it terminates when it is done The function/process will automatically exit once all work is completed.

this the bit of code where i use deno.exit, if i remove it MONGO_URL will give an error

Yeah looking at the code it looks like you want to abort execution when MONGO_URL is not set. So if we cannot use Deno.exit() we need to use something else to abort execution there. If we just remove it, then it would continue to run. What you normally do is wrap this part in an if-else statement or even a function.

if (!MONGO_URL) {
  console.log("No mongo url found")
} else {
  await mongoose.connect(MONGO_URL);
  // ...etc
}
// END OF FILE

if (!MONGO_URL) {
  console.log("No mongo url found")
} else {
  await mongoose.connect(MONGO_URL);
  // ...etc
}
// END OF FILE

The same written as a function:

async function bootServer() {
  if (!MONGO_URL) {
    console.log("No mongo url found")
    return
  }
  await mongoose.connect(MONGO_URL);
  // ...etc
}

await bootServer();
// END OF FILE

async function bootServer() {
  if (!MONGO_URL) {
    console.log("No mongo url found")
    return
  }
  await mongoose.connect(MONGO_URL);
  // ...etc
}

await bootServer();
// END OF FILE
