I am not able to get the event coming from API Gateway

I'm my current operation I want to get the API Gateway event and use a custom header to find the key to my S3 bucket. I have tried a lot of ways and all of them are failing on return.

Steps to Reproduce

Create a JavaScript Lambda with Mockoon Serverless

import { S3Client, HeadObjectCommand, GetObjectCommand } from "@aws-sdk/client-s3";
import {MockoonServerless} from '@mockoon/serverless';

const client = new S3Client({});
const bucket = process.env.DEFINITIONS_BUCKET;
const key = 'mackoon-cli-environment.json';

const { ContentType } = await client.send(new HeadObjectCommand({
    Bucket: bucket,
    Key: key,
}));

const s3Object = await client.send(new GetObjectCommand({
	Key: key,
	Bucket: bucket
}));

console.log('CONTENT TYPE:', ContentType);
const mockEnv = JSON.parse(await s3Object.Body.transformToString());
const mockoonServerless = new MockoonServerless(mockEnv, {
    logTransaction: true,
    envVarsPrefix: '',
    enableAdminApi: true,
    disableTls: true
});

export const handler = async (event) => {
  console.log("EVENT: " + event.headers['x-source-location']);
  return await new Promise(handler => mockoonServerless.awsHandler());
};
// export const handler = mockoonServerless.awsHandler();

If I comment out the above and just use the one suggested in documentation it will work. Is there a good way for me to get the events and then execute the Mockoon Serverless application.

Thanks @255kb for your response,
Apologies I didn't return earlier.
The code suggested above didn't work for me. I think awsHandler() was having issues within Async block.
This workaround worked well though for me:

export const handler = async (event) => {
console.log("EVENT: " + event.headers['x-source-location']);
return await mockoonServerless.awsHandler()(event);
};

I think this might be a useful update to the documentation to add this block of code for people who want to use it. Happy to provide a MR with the changes.

I never tried using an async handler, but wouldn't this be enough?

export const handler = async (event) => {
  console.log("EVENT: " + event.headers['x-source-location']);
  return mockoonServerless.awsHandler();
};

Great to know it works!
Feel free to open a PR to update the serverless package's readme.
Thank you.

Hi @255kb ,
I have tried to push my feature branch into the project but seems I don't have access to create the feature.

Hi, you won't be able to push to this repo as you don't have the rights.
You forked it, so you must create a branch on your fork, commit and push. Then you open a pull request on this repository, asking for a merge of your fork's branch.
