Intune OMA-URI Preferences Error

 "dom.disable_window_flip": {
       "Value": true,
       "Status": "locked"
     },
   "dom.disable_window_move_resize": {
       "Value": true,
       "Status": "locked"
     },
"network.http.http3.enable": {
       "Value": false,
       "Status": "locked"
 }

I am trying to configure our Firefox configuration via Intune and need to use the OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/Preferences with the following JSON: <enabled/> <data id="JSON" value=' { "dom.disable_window_flip": { "Value": true, "Status": "locked" }, "dom.disable_window_move_resize": { "Value": true, "Status": "locked" }, "network.http.http3.enable": { "Value": false, "Status": "locked" } }'/> I do not have any of the Deprecated preference settings in use. The error presented is -2016281112 and checking the respective settings in about:config on a synchronised device shows that the settings have not applied. Any help would be appreciated. Thanks!
