lambda : Error deploying docker lambda function

### Describe the bug

I am trying to deploy a dockerized lambda function.

This is my code:

```ts
const leaderboardsStreamHandler = new lambda.Function(this, 'leaderboardsStreamHandler', {
functionName: 'leaderboardsStreamHandler',
code: lambda.Code.fromDockerBuild(path.resolve('resources/lambdas-code/leaderboardsStreamHandler')),
handler: lambda.Handler.FROM_IMAGE,
runtime: lambda.Runtime.FROM_IMAGE,
environment: {
'TABLE_NAME': props.leaderboardsTable.tableName,
'STAGE': props.STAGE.toLowerCase()
},
logRetention: RetentionDays.ONE_WEEK,
description: 'Lambda function responsible for inserting participants in the Leaderboards table'
})
```

The Image build completes succesfully, but I get the error reported below:

Why is this happening? It doesn't make any sense :/

### Expected Behavior

I am following the documentation, so it should work just fine TBH

### Current Behavior

I get the following error:

```
Error: handler must be `Handler.FROM_IMAGE` when using image asset for Lambda function

Reproduce the failure with cdk deploy using the stack trace entry points lib/lambdas/leaderboards-stream-lambda-stack.ts and bin/leaderboards.ts. Then inspect aws-lambda's verifyCodeConfig behavior for the Docker-built code and compare it with the documented configuration; done means the deployment succeeds or the required configuration is clearly documented and covered by a regression test.
