Scheduled Lambda timeout error 504 after execution

## Bug Report

**Current Behavior**
A few seconds after a scheduled lambda is successfully executed an error occurs and will be displayed in console:
Failed to execute scheduled function: [emitStatistics] Error: Error: [504] - Lambda timeout.
It seems that serverless-offline can't handle the scheduled lambda in offline mode.
After deploying everything works fine.
There's a stackoverflow article with the same described problem:
https://stackoverflow.com/questions/76415087/serverless-offline-lambda-timeout-504

- file: serverless.yml
```yaml

plugins:
- serverless-offline

provider:
runtime: nodejs16.x
stage: offline

functions:
emitStatistics:
handler: src/handler/stats/handler.emitStatistics
events:
- schedule: rate(1 hour)
```

- file: handler.js
```js
export function emitStatistics(event: APIGatewayProxyEvent, context: Context) {
invokeWithDatabase(event, context, (conn) => handler(event, conn).emitAll());
}
```

**Expected behavior/code**
No error occurs after scheduled lambda is executed

**Environment**

- `serverless` version: 3.33.0
- `serverless-offline` version: 12.0.4
- `node.js` version: 16.20.0
- `OS`: macOS 13.4.1

**Additional context/Screenshots**

Start by reproducing the scheduled emitStatistics function from serverless.yml with the handler shown in handler.js, using serverless-offline in offline mode. Trace why the successful invocation later reports a 504 timeout, then verify that the same schedule completes without the console error while deployed behavior remains unchanged.
