Google Apps Script Propertiesservice - Confused By Unreliable Executions Logging & Editor Debugging

I find PropertiesService to be unreliable, but probably I'm just not familiar with Google Apps Script or Stackdriver and made a mistake or assumed something here that may caused th

Solution 1:

• For relatively better and reliable logging, Use Stackdriver directly(i.e., View> Stackdriver logging) rather than from the "executions" page in the dashboard. To do this, you need to switch Google cloud project from default to standard by setting a custom project number in Resources > Cloud Platform project > Change project.

• When logging objects, You must always JSON.stringify the object before feeding it to console. props.toString() will only return [object Object] as that is it's internal structure.

/*<ignore>*/console.config({maximize:true,timeStamps:false,autoScroll:false});/*</ignore>*/const props = {a:1};
console.log(props.toString());//[object Object]console.log(JSON.stringify(props));//{"a":1}

Solution 2:

This seems to work just fine:

functiontestprops() {
  let sp = PropertiesService.getScriptProperties();
  sp.setProperties({'somekey': Utilities.formatDate(newDate(), Session.getScriptTimeZone(), "yyyy:MM:dd HH:mm:ss")});
  let props = sp.getProperties();
  SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(props.somekey), "View Properties");
}
