get blows up when trying to extract path from a null value - failed gracefully in 1.2.0 #36
Description
I recently upgraded to 1.3.1 so I could use this library with Typescript, but it seems like what used to fail gracefully is now blowing up.
If I have an object like:
{
id: 1234,
employee: null,
created_on: 2021-05-11
}
With 1.2.0 - if I tried to get the field "/employee/st_price" - it would fail gracefully and return undefined
With 1.3.1 - it blows up saying it can't find "st_price" in null
Uncaught TypeError: Cannot read property 'st_price' of null
