Internal Server Error Unhandled Exception -Passing parameters from Javscript to HTML webresource

Hi All,

I am trying to pass some parameter values from javascript to HTML (open new window with queryparameters)

https://mycrm.crm5.dynamics.com/WebResources/new_CRMWebresource?customer1="+custName+"&customer2="+custName1,"_blank"

while passing this url parameter . I got the below error in that html page

Internal Server Error Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: System.InvalidOperationException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #97F7EC31Detail: -2147220970 System.InvalidOperationException: Microsoft Dynamics CRM has experienced an error. 2Z

How to resolve this ?

Regards

Felix
