For some reason you have to specify block signature, doesn’t seem to be able to
work it out despite the example showing it should and your second example
showing it does. The ‘_’ in the ‘()->_’ is usually a hint it’s a bit confused.

Thank you Roland. Beautiful!!! I got close with the block signature, in my
many attempts , but always had it “generic” which I now realize needed to be
more specific.
