Error description

  • When editing or creating a rule with a backslash character
    " \ " (such as in a file path name) in the AQL rule filter, a
    parsing error similar to the following can be displayed:
    "There was a problem parsing the AQL query. Invalid escape
    sequences detected."
    For Example:
    Have a rule, and in the condition for the AQL Filter click
    "this" to enter the AQL In the pop-up entry field: Enter an AQL
    filter query: Enter "Process Commandline" ILIKE '%C:\Program
    Files%'
    Result - The query fails to save due to a parsing error:
    "There was a problem parsing the AQL query. Invalid escape
    sequences detected."

    As in the example above:
    "Process Commandline" ILIKE '%C:_Program Files%'
