Reading Books crashes the client

[dekrom]

I've been using the project for some time and when I try to read any book (Doesn't matter how long is it) as soon as I do the secondary click to get the book data my proxy freezes and gets kicked out the server.

Can reproduce, the first time the proxy started trying to reconnect but the client didn't get disconnected from it. The second time, as soon as I right clicked, the proxy started doing the same and my client got kicked with the caption "Proxy restarting..."

[unclamped]

This is the only error I found in the logs related to this:
[kick_disconnect] {"reason":"{\"color\":\"red\",\"text\":\"An internal error occurred in your connection.\"}"}
