I need to filter event by Amplitude user property Server upload time, so i use such params:

params = {
  "event_type": "Page_view_PAD",
  "filters":  
    {
      "subprop_type": "user",
      "subprop_key": "Server%20upload%20time",
      "subprop_op": "greater",
      "subprop_value":  
        "2024-08-15 11:57:56"
      ]
    }
  ]
}

Response is ‘HTTP 400: Bad Request’.

When i filter by another property, it returns correct data.

I tried to use property name without URL-encoding:

"subprop_key": "Server upload time"

But it also doesn’t work.
Please, help.
