You would have got “An unknown failure has occurred…” many times in your portal when there was exception thrown by your Dynamics CE plug-in code.

Now in Dynamics Portals, we can show the plug-in error in following portal screens by adding “Site/EnableCustomPluginError” entry in Dynamics CE Portals -> Site Settings

• Entity list
  • Retrieval of records
• Entity form
  • Retrieve
  • Create/Update and so on
• Web forms
  • Retrieve
  • Create/Update and so on

Lets see the approach and steps.

• I have created and registered a plug-in with logic to intentionally throw an exception on ‘Case’ Create.

• Go to your Portal and try to create a Case and you would get below generic exception “An unknown failure…”

• Now open your Dynamics CE application, navigate to Portals -> Site Settings and create a new Site Setting with Name “Site/EnableCustomPluginError” and Value true.

• Go back to your Portal and try to create a Case and you would get actual Plug-in error.
