When I run validation on my process in workbench, I get a warning [WBP-170] Warning: The variable '[name of var]' is not referenced in the process '[name of process]'. The variable is referenced in a query single action using the syntax where you embed the variable in the sql to execute using {$ /process_data/@[name of var] $}. Anyone else experiencing the same issue? Anyone know where I can report the bug?
