The below error message occurs because there is too much data to render and subsequently it times out:
System.Web.HttpUnhandledException' was thrown. ---> System.Web.HttpException (0x80004005): Maximum request length exceeded.
We have been able to replicate this issue on our local RIO. This is currently with our Development Team to review and confirm.
We will update you once we know which release this fix will be included in.
As a workaround, please type talk to a person and the Digital Assistant will put you through to a live support agent. They will then be able to run a data fix to close the stream or end the clinic stream slots.
