I truly hope you don’t end up getting this error:
1 2 3 4 5 6 7 8 9 10 11 Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=126.96.36.199, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: An unexpected error occurred.Detail: <OrganizationServiceFault xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/xrm/2011/Contracts"> <ErrorCode>-2147220970</ErrorCode> <ErrorDetails xmlns:d2p1="http://schemas.datacontract.org/2004/07/System.Collections.Generic" /> <Message>An unexpected error occurred.</Message> <Timestamp>2011-06-07T21:47:31.4167053Z</Timestamp> <InnerFault i:nil="true" /> <TraceText i:nil="true" /> </OrganizationServiceFault>
I’m not sure why, but this exception seems to overwrite all of my tracing text. This error is basically a catch all of it can’t figure out what type of exception your plugin is throwing. Turns out that I was trying to generate a report in SSRS that was invalid (a relationship changed in CRM, but the report hadn’t been updated). The report caused a cataclysmic effect and the plugin crashes.
Event viewer wasn’t very helpful, and the tracing in the C:\Program Files\CRM Install\Trace wasn’t very helpful either. It was an easy fix for me (because it worked on at least 1 entity and I was able to narrow it down easily), but another option would be to comment out code until you start to get some tracing again.
Hope this helps!
