With neos/fluid-adaptor 4.2, this doesn't work anymore and I guess because of the refactor to static function https://github.com/neos/fluidadaptor/blob/c025cc4c13f9e35a3363cfca02af832e6350a3bb/Classes/ViewHelpers/Uri/ResourceViewHelper.php#L108

Do you know the solution?

You should use https://github.com/Flowpack/Flowpack.CacheBuster instead.
It also doesn't rely on fluid anymore.

Works like a charm 👍

Thanks a lot :)
