Is there a limit on data returns from the server?
Yes, server functions can return up to 4MB. Media objects are streamed, so if you want to return more than 4MB, package it up into a Media object.
I think we’ll need more information if we’re going to track down your problem. Can you share any details that would enable us to reproduce it? What is in these dictionaries?
If you can strip your app down to something simple that has the problem but doesn’t reveal any sensitive data, that would be really helpful.
