Were you using the wrappingkey name as is in place of publickey.bin?
Just rename the wrappingkey file to something simple : Example: mywrap
I have seen errors happen if you just use the same name . It might be because there are multiple characters such _ ,- which might be breaking up the command.
I ran into the same error. Through research, I identified spacing as the issue. Removing the spaces between commands worked for me. When copy over the command be sure to remove any spacing between the lines.
