In this gist
See the transform_output.mlir and pdl_output.mlir,
It appears the transform output runs into the error with expecting particular type of stream buffers
Here is a full IR dump as well.

FYI @MaheshRavishankar
Also @qedawkins (for help on changing the custom dispatch if thats the right thing to do)
and @benvanik if the error in the full dump is a bug.
