discord.errors.HTTPException: 400 BAD REQUEST (error code: 50035): Invalid Form Body
In rate_limit_per_user: int value should be less than or equal to 21600.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

How can we reproduce this issue?

use [p]slowmode 31536000 or some other value larger than 6 hours,
