I've been tinkering with some pipeline modules for the Statiq generation engine that I use to render this blog, and I bumped into a fun mistake in my code which confused me for a while. To help me next time I'm doing this sort of modification, this seemed worth documenting - even if it is a bit of a silly mistake...
A common but not-fun issue for working developers is when you do some work, test it locally, submit a PR and then find that it blows up on someone else's computer. I'm not too proud to admit that I had an issue with this recently, which highlights a thing you have to remember when working with Sitecore Content Serialisation.
