"JS_Parse_Error [SyntaxError]: Unterminated string constant" In moment.js During Bundle

[sprankhub]

When I run magepack bundle, I get the following error:

Node.js v18.16.0

This happens after a big update from Magento 2.4.4-p4 to 2.4.6-p1 including Node package updates, especially a MagePack update from 2.8.0 to 2.11.2.

I debugged this and found out that the error happens for lib/web/moment.js. As soon as I remove the mapping moment: 'moment' from my magepack.config.js, the error is gone. I verified that the file exactly matches https://github.com/magento/magento2/blob/2.4.6-p1/lib/web/moment.js.

Any idea?

I noticed that pub/static/frontend/Magento/shoptheme/de_DE/moment.min.js is already broken. Looked into the static content deployment output and found a lot of "Unclosed regex pattern at position" errors. This was caused by tedivm/jshrink version 1.6.7. Updating to 1.6.8 solved the issue. See tedious/JShrink#135.
