WeatherMap editor and php 8.1 : incompatibility?

Mine is throwing the following error when I try to access the editor:

{
“message”: “Attempt to assign property “configline” on null”,
“exception”: “Error”,
“file”: “/opt/librenms/html/plugins/Weathermap/lib/Weathermap.class.php”,
“line”: 1840,
“trace”: [

}
]
}
