req empty in Function

const requestBody = JSON.stringify(req.bodyRaw);
log('Request body:', requestBody);

const requestJson = JSON.parse(requestBody);
log('Request JSON:', requestJson);```

Which results in:
```Request method:
Request body:
Request JSON:```

From my frontend I call the function like this:

```functions.createExecution(
  'function-id',
  JSON.stringify({
    foo: 'bar',
    lorem: ipsum,
  }),
  false,
  '/',
  ExecutionMethod.POST,
  {
    'content-type': 'application/json'
  }
  ).then((response) => {
    console.log(response);
  }
);```

Is there anything that I'm not seeing and doing wrong?
