Empty `result` array with "1 package(s) found" message for SAP Machine JDK 21 on Windows

I'm using the following URL:
https://api.foojay.io/disco/v3.0/packages?jdk_version=21&latest=available&package_type=jdk&distribution=sap_machine&archive_type=zip&operating_system=windows

And I get what seems to be 1 result (which is expected), but... it's not there:
```
{
"result": [],
"message": "1 package(s) found"
}
```

Could you please check what's going on?
