Whiteboxgui via Jupyter notebook

[sanimorla]

I am trying to use the whitebox tool, ClipLidarToPolygon, via whiteboxgui on Jupyter notebook but when I run it, I receive the message below:
"thread 'main' panicked at 'index out of bounds: the len is 0 but the index is 18446744073709551615', whitebox-lidar\src\las.rs:713:31
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace"

And, when I try using the same tool on the command-line interface with the code (example), .\whitebox_tools -r=ClipLidarToPolygon -v --wd="D:\clipALS\" -i='Transact 4_CutResult_1_3_0.las' --polygons='20m_R_shp.shp' -o='output.las' I receive similar message as below:
"thread 'main' panicked at 'Tool run with no parameters.', whitebox-tools-app\src\main.rs:72:21
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace"

How can I fix this, please?
