Local keyword comes from a different shader

Enabling application space warp in build apk yields the following error :

Unity version : 6000.0.61f1
XR Target : Oculus - 4.5.2 ( included the following : low overhead mode , optimized buffer discards , symmetric projection , fixed foveated rendering using unity api for urp , depth submission , late latching , target devices all , experimental appsw active
URP branch : 6000.0/oculus-app-spacewarp

Edit : looks like the string is empty , i just fixed it by adding safety check , doesn't seem to effect space warp .

var kv = data.subsampleDepthKeyword;

// Debug.Log($"kv name:'{kv.name}' ToString:'{kv.ToString()}'");

if ( ! string.IsNullOrEmpty(kv.name) )
{
    data.xrMotionVector.EnableKeyword(kv);
}
