@BulkBeing thanks for making the change. It seems failing the monovertex e2e test. Since the test executes the mono vertex which is written in Rust, I suspect it might related to the image build change in the PR. Please check. You can run make TestMonoVertexWithTransformer locally to execute the test. Thanks!

A new PR (#1958 ) was created with the same changes since I was not able to figure out why the CI pipelines were failing here. Tried smaller changes at a time in the new PR. The tests were failing because the numaflow-rs binary didn't had executable permission within the image. Will do further follow ups in the new PR
