Hello 😊

I tried to reproduce your usecase as close as possible.

Here is the code block I propose:

```auto
const mainJson = $('Set').all()[0].json;
const resultJson = {};

const keys = Object.keys(mainJson);
keys.forEach(key => resultJson[key] = mainJson[key].filter(value => !!value));

return [{"json": resultJson}];

```

And here is the result:

You can also play with the workflow here:

Don’t hesitate to check input data with `console.log` !  
It helps a lot for debugging this kind of situation 😉
