What about debugging?  I can't seem to trigger breakpoints in the TS source.  I can only trigger breakpoint in the compiled js in VSCode.

Yes that was done, however, I did not embed the jar per h_kataria's comment below, so that's probably the issue.  I had assumed that the jar is available OOTB. <embedded> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.resource.filter</artifactId> <target>/apps/<your-project>/...

Ah maybe that's it, I added the dependency but i did not embed the bundle, I will give that a try.  Thanks all.

I followed this article to try to use Resource Filter Stream, project builds and deploys fine, however rfs is always null, any ideas?  Am I missing something?  Thanks in advance. ResourceFilterStream rfs = resource.adaptTo(ResourceFilterStream.class);
