Resolution:

This error occurs when the elasticsearch-users tool is parsing the input and finds unexpected arguments. This can happen when there are special characters used in some of the arguments. For example, on Windows systems the , character is considered a parameter separator; in other words -r role1,role2 is translated to -r role1 role2 and the elasticsearch-users tool only recognizes role1 as an expected parameter. The solution here is to quote the parameter: -r "role1,role2".
