Research direction

Reproduce the issue with a script element pointing to an empty /scripts._hs file, then inspect the parser path shown in the hyperscript-0.9.5-2839a7f.js stack trace, especially raiseParseError and parseElement. Done means an empty external hyperscript file no longer throws the reported RangeError.

Written by the indexing model from the issue text.

Description

Adding e.g. <script type_="text/hyperscript" src="/scripts._hs" /> when scripts._hs is empty results in e.g.

Uncaught (in promise) RangeError: Invalid count value
