2.6.0 gives entrypoint missing error during packaging

[bpringe]

With the Calva extension, version 2.6.0 of vsce causes the following error when running npx vsce package --githubBranch published:

 ERROR  Extension entrypoint(s) missing. Make sure these files exist and aren't ignored by '.vscodeignore':
  extension/out/extension

When I use vsce version 2.5.3, packaging completes successfully.

For more context, Calva's .vscodeignore blacklists everything and then whitelists files.

# Put everything on the blacklist by default
*
*/**
**/.DS_Store
*/**/.DS_Store

# Whitelist
!language-configuration.json
!clojure.tmLanguage.json
!assets/**
!out/**
!package.json
!README.md
!CHANGELOG.md
!LICENSE
!clojure-lsp.jar
!deps.clj.jar
!bundled/**

It seems like !out/** would cause extension/out/extension to be included, but maybe I'm missing something? I'm assuming the context of the .vscodeignore is within extension/. Is that correct?

I don't know how I didn't notice that. Thanks for informing me.
