Thanks! It looks like it's having trouble accessing document: https://github.com/snowpackjs/astro/pull/1445/checks?check_run_id=3724759035#step:9:404

The Lit renderer installs Lit's window shim on the global so it should be there: https://github.com/snowpackjs/astro/blob/main/packages/renderers/renderer-lit/server-shim.js#L1

Might need to debug why we are getting this error.

[stramel]

@matthewp It seems strange that it passed on Node v12 to me but not Node v14.

I will keep trying to dig into it

[stramel]

@matthewp Seems all the errors stem from an update to @lit-labs/ssr. Everything passed with Lit v2 update by itself

[stramel]

@matthewp Sorry for all the pings. I found the root cause but I'm not sure what solution we want to go with.

Root issue: @lit-labs/ssr no longer shims window.global to window. lit/lit@2043eb0

So by adding window.global = window after the shim is installed, everything works. This feels very hacky to me.

I'm also quite confused why all React, Vue, Preact, and Markdown are all reliant upon this shim being installed in a test. Seems to me that this is just bad setup for those tests. If they were to run before that shim were to be installed, they would all fail as they are currently.

[matthewp]

Thanks for the research @stramel!

I don't think that those other tests need the shim, but rather that the existence of the shim causes their code to branch (due to some feature detection I imagine). So this is kind of a good thing, because it's catching "what happens when you have Lit & React/etc. in the same project).

I'm fine with adding the window.global if that's all it takes.
