I get error like this.

I get nydusify images by this command:

$ nydusify convert --source abushwang/redis:$source_tag --target abushwang/redis:$source_tag-nydusify

nydusify comes from this:

$ wget https://github.com/dragonflyoss/nydus/releases/download/v2.3.0/nydus-static-v2.3.0-linux-amd64.tgz

I have add --compressor, but not work

$ nydusify convert --compressor none --source abushwang/redis:$source_tag --target abushwang/redis:$source_tag-nfy_lz

...

$ nydusify convert --compressor lz4_block --source abushwang/redis:$source_tag --target abushwang/redis:$source_tag-nfy_lz

@cslinwang PTAL.
