I recorded the script in URL based scripts work perfectly fine in VUgen now I run the same script in controller.Iam getting the following error.

-27190 : Action1.c(423): Error: No match found for the requested parameter "WCSParamContext_URL2". If the data you want to save exceeds 4000 bytes, use web_set_max_html_param_len to increase the parameter size

I used 10 vusers out of which 7 gets passed.

Can some one please help on this
