Stimulsoft pdf export exceed cookie size - asp.net

Question

I'm trying to export my report into PDF.
I'm using ASP.NET as my backend and the problem happens after I pass the report to a controller method.
I get this error:
$exception {"The value size of the cookie is '..........'. This
exceeds the configured maximum size, which is
'4096'."} System.Net.CookieException
right here:
I've used chrome debug mode for cookie and I get this :
