This bug also impacts main with eldritchv1 reverse shell, likely a js / server side issue.

The likely culprit, this needs to be increased. @hulto what size is the max we want to allow?

[hulto]

Probably like the size of a tome?
I think 100,000 bytes would be more than enough. A longish tome is 12,000 bytes
