Bug: Statically sourced projects widget cannot fetch projects

The static source feature on the featured projects widget no longer works as of 0.0.218.

The error message is as follows:

caught (in promise) TypeError: Failed to construct 'URL': Invalid URL
    at extractWorkingGroupIdFromUrl (main.js?v1.0?v=1682106222:6162:10)
    at _callee2$ (main.js?v1.0?v=1682106222:6229:26)

This currently impacts eclipse.org/research if we were ever to upgrade to a newer version of EFSA.
