<cite>sipoyraj: </cite> I didnt find any Logs folder under web project
Logs folder is hidden in visual studio solution explorer by default. Select WEB project, Use show all files menu in the top right side of solution explorer . Then you can see the Logs folder. Inside you can find the Logs.text.
Or
You can navigate to Web project solution folder in windows explorer to find the same.
Experiencing the same issue. Can't execute logout, same error especially in chrome. Hope you will consider this case (Format Exception) in next build.
