Trouble with a null reference to an object resolved via the Secret

[ericrwhite]

I'm having trouble setting a property. the JS script I have results in the following output (the pertinent JS script itself is below the output). From the Secret, the code clearly gets the Public but then seemingly cannot get a publicKey property from the resulting object resolution. Something similar happens using the Stellar Laboratory (with less detail).

I'm an old coder, any help would be greatly appreciated.
