Temp table does not exist

[rupeshtarwade]

I am getting below error. This was working fine when I implemented it, but now it throws an exception about temp table. Can you put some light on this on how I should modify my code to get around this? Thank you for your time and assistance.

The ErrorWrappingMiddleware caught an unhandled exception. This is a bug.
