GAS - data error for ScriptProperties.setProperty("myName", null);

I am trying to learn about the ScriptProperties object in GAS.

I tried setting a property to a value of null, and I get an error.

I can understand if like JavaScript, setting a value of null undefines that property.

But why are you disallowing this value? It seems reasonable (to me) to allow a script to undefine a script (or user) property.

Another question about ScriptProperties (and I assume the same holds for UserProperties), Why when I display the value of an undefined property it displays as "undefined", but when I try to test for the value "undefined" (without quotes) it does not match?

It seems, that if you are going to introduce a new special attribute value of "undefined", it should be consistent through out the system. If by "undefined" you mean null, well then why not display it with the word "null"?

I am just trying to learn about this new environment. All help is appreciated. Thanks for your support.

There is an open feature request to add support for removing properties, which you can star for updates.

The value "undefined" is not a string but rather a special value built in to JavaScript. You can refer to it like "null":

if (foo == undefined) { ...

More information is available on the w3schools page.
