"Caught Exception While Emitting to Sink" Error

Problem

When you try to view the HotDocs Advance log files, there is no logs folder in the standard location. When you check the Windows Event Viewer, you see the following message:  

"Caught exception while emitting to sink Serilog.Sinks.RollingFile.RollingFileSink: System.UnauthorizedAccessException: Access to the path 'C:\inetpub\wwwroot\Logs' is denied."

Cause

This error is typically caused when the IIS user under which Advance runs does not have permission to create and write to the log folder.

Solution

  6. Make a note of the user account that appears in the Identity field.

2. Give the user appropriate permissions to the Advance deployment folder

  1. Open Windows Explorer.
  2. Navigate to the HotDocs Advance deployment folder; by default, this is C:\inetpub\wwwroot\.
  3. In the folder, right-click and select New > Folder.
  4. Type Logs as the new name of the folder.
  5. Right-click the new Logs folder.
  6. Select the Properties option.

  8. Click the Edit button.
