+title: "Content Frontmatter Causes `astro build` Error?"
+date: 2024-11-24
+---
+
+Another entry for this site. I ran `pnpm run build` after adding yesterday's entry, and got this error:
+
+```
+✘ [ERROR] The build was canceled
+
+end of the stream or a document separator is expected
+  Hint:
+    Browser APIs are not available on the server.
+
+    If the code is in a framework component, try to access these objects after rendering using lifecycle methods or use a `client:only` directive to make the component exclusively run on the client.
+
+    See https://docs.astro.build/en/guides/troubleshooting/#document-or-window-is-not-defined for more information.

+
+I was obviously not using Browser APIs in an `.md` file. But, it did report that file as the culprit (specifically, the first line), so I checked it out.
+
+```md
+---
+title: @astrojs/node Build Error
+date: 2024-11-23
+---
+
+<... rest of the file...>
+```
+
+I noticed the `@` was a different color than the rest of the line. I thought YAML interprets any non-digit character as the start of a string; but just in case I wrapped the line in quotes, and it worked!
