Vugen correlation issue on Error -35049

Hi,
 
I'm new with loadrunner. I've installed loadrunner version 12.01 in a windows 2008 with java (build 1.8.0_25-b18) installed.  I'm running a proprietary application  using chrome. When I run Design studio for correlations, when scan second time the error -35049: "No match found for the requested parameter "CorrelationParameter". Check whether the requested regular expression exists in the response data   [MsgId: MERR-35049]" is raised for below line:  web_custom_request("dashboard_7"
 
I do not undertand since there´s no need to correlate this part.  Could you support me?
