<div dir="auto">Adam is exactly correct here. You're trying to call server code in a web view.

in more detail: it is expected that the Ur/Web compiler give that
kind of terrible error message in many cases that don't nest
server-side and client-side code properly. Some day it should be
enforced with a type system, yielding better error messages, but
that day is not yet upon us!<br>

<div>ok so this was itching me so I decided to try to isolate
whatever is at fault. and I think I created the simplest
sample to reproduce the problem:</div>

<div><a href="https://github.com/fabriceleal/urweb-test" target="_blank" rel="noreferrer">https://github.com/fabriceleal/urweb-test</a></div>

<div>so I'm assuming the problem is not at my end and will try
to do the parsing on my own until the urweb-regex lib gets
updated<br>

<div>I'm having this weird error while trying to
compile urweb using urweb-regex; if I isolate that
page in a separate module, it compiles fine (even
though I seem unable to access that page from the
browser), so I assume I'm doing something wrong in
my helloworld.ur file. <br>
</div>
<div><br>
</div>
<div>Would appreciate some pointers; Source file is
this one (<a href="https://github.com/fabriceleal/urweb-experiments/blob/doesnt_compile/helloworld.ur#L869" target="_blank" rel="noreferrer">https://github.com/fabriceleal/urweb-experiments/blob/doesnt_compile/helloworld.ur#L869</a>)
and I also included the result of -dumpVerboseSource
(<a href="https://github.com/fabriceleal/urweb-experiments/blob/doesnt_compile/dumpVerboseSource.txt#L7705" target="_blank" rel="noreferrer">https://github.com/fabriceleal/urweb-experiments/blob/doesnt_compile/dumpVerboseSource.txt#L7705</a>)</div>

<div>That FFI maybe_onload is particularly suspicious
... is the call to parsePgn being "lifted" to
javascript code? Some time ago I had some errors
while trying to use the rpc function in the loadPost
page because i was mixing it with code that uses my
canvas library which has a bunch of clientOnly FFI
calls; I reorganized my code and eventually made it
work nicely (<a href="https://github.com/fabriceleal/urweb-experiments/commit/503da7e28f1a05be6e69e9f60c9cd321bfa252ce" target="_blank" rel="noreferrer">https://github.com/fabriceleal/urweb-experiments/commit/503da7e28f1a05be6e69e9f60c9cd321bfa252ce</a>
IIRC). I tried to isolate the testParse function but
seems to not lead anywhere.</div>
