Package: libjs-vue-router Version: 3.4.9+ds-1 3.4.9+ds-1 packages an incompatible version of path-to-regexp. This was reported and fixed in bug #927254, but is now reproducible again in version 3.4.9+ds-1.
Specifically, the tokensToRegExp function is lacking the attachKeys wrapper around its return value. >From upstream 3.4.9: function tokensToRegExp (tokens, keys, options) { [...] return attachKeys(new RegExp('^' + route, flags(options)), keys) } >From 3.4.9+ds-1 function tokensToRegexp(tokens, keys, options) { [...] return new RegExp(route, flags(options)); }
