Server Error with Anonymous Access

[cschnell]

 We're using Jasperserver 6.4.2 community version.  I'm trying to give access to the anonymous user so that they can run a report from within another program on our server.  I have followed the instructions from this question: https://community.jaspersoft.com/questions/847771/anonymous-access-jasperserver-601

Including the changes to the files mentioned in this article: https://community.jaspersoft.com/wiki/allow-anonymous-access-reports

When I try to run the report using this URL, I get the below error.

http://localserver:8080/jasperserver/flow.html?_flowId=viewReportFlow&_flowId=viewReportFlow&ParentFolderUri=/reports/Order_Sheet&reportUnit=/reports/Order_Sheet&standAlone=true&j_username=anonymousUser&j_password=

Server Error

Error Message

There was an error on the server. Try again or contact site administrators.

 

 

Any help would be appreciated.
