[Bug] Can't reverse image search by hash

I am getting an error when performing a reverse image search only by MD5 hash on https://danbooru.donmai.us/iqdb_queries and https://betabooru.donmai.us/iqdb_queries

Example hash value: 83c2f56cce52ee4b228d5bffe317c8dc

Gives error:

An unexpected error has occurred.

Details: ActionDispatch::Cookies::CookieOverflow exception raised.

app/logical/rack_server_timing.rb:19:in `call'

I tried md5:83c2f56cce52ee4b228d5bffe317c8dc on the IQDB page hash text field, but it still fails. A normal post search with md5:83c2f56cce52ee4b228d5bffe317c8dc works.

The hash of the IQDB endpoint is not the md5 hash, it's the IQDB hash. It's the field you see here.
