Description

When then content of a whiteboard is too big, it is not possible to download its content as PDF.

The User gets disconnected from the Server with the Message: The connection to the server has been lost. And nothing is gets download. This sometimes also happens for download as PNG.

This is from the log when it happens:

13:07:59.765 o.a.o.w.c.OmWebSocketPanel:173 [nio-5443-exec-7] - WebSocketBehavior::closeHandler The client closed its connection with code '1009' and message: 'The decoded text message was too big for the output buffer and the endpoint does not support partial messages'

You can use the attached PDF for testing. I upload it to the whiteboard and then try to download it as PDF.
