This article only applies for WorkflowGen version 5.6.2 and earlier.  
As of version 5.6.3, RAISEEXCEPTION doesn’t use authentication parameters defined in the workflow application and in the `web.config` file.

### Issue

When you launch a RAISEEXCEPTION action an error is triggered with the following error displayed in the Portal Action Follow-up form:

```auto
CODE : ErrorWebprocCall (#205)SOURCE : WebProcExecuteMESSAGE : Error Unauthorized ....

```

### Solution

1. Edit the RAISEEXCEPTION configuration file (`/wfgen/wfapps/webservices/raiseexception/web.config`) and check the following entries:

2. Add the following entry in the same `web.config` file if not already defined:

### Notes

- The RAISEEXCEPTION workflow application has to be secured with Basic authentication; form authentication is not supported. The same authentication requirement applies to all workflow applications in the `/wfgen/wfapps/WebServices` folder.

- For WorkflowGen versions prior to v5.6.3, the RAISEEXCEPTION workflow application doesn’t work when the WorkflowGen Portal is secured with Form authentication.
