Making an attempt to paint rows based mostly off of the worth of the “Standing” column

Nevertheless I can’t get it working because it retains giving the next errors:

TypeError: Can not learn property ‘model’ of null

TypeError: Can not learn property ‘model’ of nullTypeError: Can not learn
property ‘_events’ of null

Debugging it, it appears to be failing on: var row = doc.getElementById(rowId); and at all times developing null.

Any concepts why it would not be capable to execute the getElementByID? This appears to be occuring whether or not I add it as a JSLink, or put it in a script or content material editor… at all times the identical error.

Code:

SP.SOD.executeFunc("clienttemplates.js", "SPClientTemplates", perform() {

SPClientTemplates.TemplateManager.RegisterTemplateOverrides({
 OnPostRender: perform(ctx) {

   var statusColors =  {
      'Pending Investigation' : '#FFF1AD',  
      'Below Investigation' : '#FFD800',
      'Accomplished' : '#01DF3A' 
   };

   var rows = ctx.ListData.Row;
   for (var i=0;i<rows.size;i++)
   {
      var standing = rows[i]["Status"];
      var rowId = GenerateIIDForListItem(ctx, rows[i]);
      var row = doc.getElementById(rowId); 
      row.model.backgroundColor = statusColors[status];
   }
 }
}); 

});
