Promise.all is only executing 1 out of 3 promises I pass to it

I have an async function, in which I take some arguments. Based on what is passed as argument, I call another function. You can consider the structure to be something like this.

async function createTaskReminder(val) {
 switch (val) {
  case 1: 
    await call1();
  case 2:
    await call2();
  case 3:
   await call3();
}

I call this async function as following:-

const result = await Promise.all([
                              createTaskReminder(1), 
                              createTaskReminder(2), 
                              createTaskReminder(3)
                      ]);

The async functions called inside createTaskReminder() perform some DB queries and possibly DB updations as well.

The problem is that in the console, as well as in the DB I can see results of calling createTaskReminder(1) only. Which means, that only the first promise is being resolved.

I tried using async.each from the async module as well, but that also had the same results.

This is actually a code being run as a lambda function in AWS amplify.

The results which I’ve been seeing are obtained when I mock the function using amplify mock function. So the DB updations which I’m talking about are using DynamoDB and graphql api service to interact with it.

I also tried to take the lambda and run it separately both in my machine locally and on google colab as well, but I got the same results.

I expect all the three promises to be running to completion, but that’s clearly not the case. Can someone please help me to resolve this issue?
