# Error: message must be shorter than or equal to 10240 characters

If you write large responses, then you may experience one of the following errors:
> An error occurred when editing/sending a message: message must be shorter than or equal to 10240 characters
---
> Your latest message was too large, please delete or edit it and try again (xxxxx chars long) (unk)


Sometimes, it is easy to get carried away, especially if you have a lot of details to take care of! 

Unfortunately, if you see either of these errors, you will need to reduce how much you are sending at once. 10,240 characters is the maximum size JanitorAI supports.
