TypeError: Cannot read property 'links' of null

I think I had this issue in the past once. Hard to know what's causing it. I have 3 navigation areas in Squarespace, one of which is all folders and external links, another of which is ALL external links. I wonder if that could be an issue?

Here's the error:

    var navContext = getNavigationContextItems( navigation, (pageLinks || navigation.links), pageJson ),

I have some issue

I think this has something to do with using a <squarespace:navigation> tag without a navigationId attribute. Any thoughts on that?
