Hi @Deng, Yiming ,
So far，I haven't heard of this error in 2016 version. How did you reproduce this issue? Could you give me specific test data and a screenshot of the error result?
Best Regards,

I Run the report from web browser.
One parameter is set to a string with length = 72487.
The log of SSRS is att92611-ssrslog.txtached.

Since there is no way to reproduce this problem, I will spend some time researching it.

Actually, the error log is always there，but there is no error message on UI if document map is deleted.
