Thanks for the report - we will have a look!

[pawelru]

if I open console I can see more detailed error message.

It all started with this:

Error fetching https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.js.metadata - <?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message></Error>

Which means that package xfun is not available in public wasm repo. It's quite surprising as this package is installable from within https://webr.r-wasm.org/latest/. I would try to update related packages and/or extensions - maybe url for wasm binaries has changed and we are pinging the old one?

https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.js.metadata is not accessible
but
https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.50.js.metadata is

any way to downgrade xfun?

Also, 0.52 was published to CRAN Apr 2nd.

Very weird indeed

https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.tgz and 0.50 both exist, so it's just a matter of the js.metadata not existing or being corrupt

An update to the r-wasm extension solves the problem

@Polkas it should be working now
