TypeError: Cannot set property urlNormalized of #<Object> which has only a getter

I’ve upgraded from 0.3.4 to 0.3.12 today and I’m encountering the issue below when I issue this command

EDIT: After testing with previous releases, The error appears from the release 0.3.11

vite build && vite build --ssr && vite-plugin-ssr prerender

I’ve both tested with vite 2.5.10 and 2.6.9 and got the same result.

After a quick search, I’ve found an issue from esbuild with similar error message: https://github.com/evanw/esbuild/issues/587

But I cannot say wether it’s related or not.

I’ve some bigger plans regarding pageContext handling that includes improve clear & helpful error messages about “wrong” pageContext handling, i.e. you are not suppose to mutate pageContext directly.

I see that makes sense. I’ll have a look and release a fix tentatively today.
