Experiencing same issue since upgrading to 3.0.0-beta.1
Only files that include *.content or *.templateContent fail when using --incremental
Removing --incremental from npx @11ty/eleventy --serve is the current workaround.

I got the same error on 3.0.0

Trying to generate pages from a collection in --incremental mode.

I have this in a web.md file

---
eleventyImport:
  collections: ["allcontent"]
pagination:
  data: collections.bookcontent
  size: 1
  alias: pageitem
layout: "web/web-all.njk"
permalink: "/{{pageitem.data.collection}}/{{pageitem.data.id}}/index.html"
---

if i update web-all.njk, i get this error.

Tried to use templateContent on unrendered template

i have this line in the web-all.njk : 

 {{ pageitem.templateContent  | safe }} 

if i remove this line from the njk files, things get updated correctly (although it seems that the updated content isn’t updated, i need to stop/restart eleventy to see the changes).
