Internal server error (500) when browsing the package page

[claui]

trafficstars

Every time I visit the page of my published package, I get:

Request failed: GET https://open-vsx.org/api/claui/packaging/0.2.1/file/README.md (Status 500)

This seems to be similar to #374.
However, I’m absolutely sure that I published 0.2.0 only once, and also 0.2.1 only once.
So I figure this is unaffected by the fix in #385. Btw, the extension works on the VS Code Marketplace.

Do the server logs say anything of interest?
