PS API - Fit image to specific size

Hi,

I created an Action JSON file which I use with the Photoshop API and send to this endpoint.

https://image.adobe.io/pie/psdService/actionJSON

However this object does not do anything (doesn't work):

{
   _obj: "javaScriptOptionsClass",
   height: { _unit: "pixelsUnit", _value: 1440.0 },
   limit: false,
   message: "Fit Image action settings",
   width: { _unit: "pixelsUnit", _value: 1080.0 },
},

How can I fit an image with the action JSON to certain dimensions?

Everything normal works, I have tested different other actions which work but not this one.

Thanks in advance!
