Turn on .net core error messages

To enable the extended error messages on your asp hosting you need to add the following line to the web.config.

 <aspNetCore processPath=".\JeProjectName.exe" stdoutLogEnabled="true" stdoutLogFile=".\Logstdout" />

After this you need to create a log folder in the root folder, you name this folder 'logs' This folder is unfortunately not created automatically. After this you can run the request again and a log file will be created in the logs folder.
