Very weird, thanks for the report 🤔
I've tried multiple scenarios, using the exact example post you shared, and many other cases, tried different versions of Node.js too, etc. but I didn't manage to reproduce the issue at all.
Would you be able to provide some kind of repro? Even if it's a small setup with a single post with the issue would be enough.
Here are a few screenshot of the debugging session
At this point, e is a string and it blows off.
The string came from .text here.

That's weird, and the versions looks good compared to a working version :thinking:
Looks like it's using yarn, could you try for testing enforcing the marked version to something like 15.0.8 using selective dependency resolutions in your package.json file:
"resolutions": {
"marked": "15.0.8"
}
The resolution rule fixed it. So there's some kind of mistmatch with marked 12 (from astro-remote) and 15 which leads to this error.
Wow, I'd been hitting this and was really stumped -- the resolution rule worked for me as well!
