getText.ts error TS2722: Cannot invoke an object which is possibly 'undefined'

[langfingaz]

Hi there!

Many thanks for developing this project. I've written a Dockerfile to create a container image and self-host the web application.

Since some changes to the Git repository, I get the following type-check error while running npm run download:tldr-pages && npm run build:sitemap && run-p type-check build-only:

src/data/tldr-pages/page/zip/zipLib/getText.ts(5,22): error TS2722: Cannot invoke an object which is possibly 'undefined'

Here is the relevant log from docker build ... (Dockerfile):

If this is too far off topic and your builds work, please don't put too much effort into this issue. But I thought that maybe this points you to some relevant error/bug in the code.
