Join the club!
See here for a possible workaround: Panic Error with .GetPage in Hugo 0.45
But this is also a bug (read further down that topic).

Argh! Annoying. Hopefully someone can put a more meaningful error message on that at some point. I’d have never found that, thanks. I will give the workaround a go now.
I believe that’s a Go limitation… If some function has nil as an argument, it goes crazy (I’m 100% sure that statement is technically incorrect :P). But I have seen this many times in different contexts, and the rule of the thumb is: Use with – Don’t assume your function arguments to be non-nil.
Already open issue to track stracktrace due to nil

Well, I couldn’t get the workaround to work in my case. Probably my brain is fried in this heat.
So I’ve killed off the offending template which was supposed to be creating a search JSON file for Algolia but I haven’t managed to get Algolia search to work anyway. A job for another time.
