Hi, I don’t think this is something that’s that high priority as it’s probably an edge case but it seems that using an author slug of length 1 breaks the Ghost Admin filter by author functionality (and by extension anything that uses the same API endpoint). If I change the author slug a slug of length 2 or higher, I’m able to filter by that author’s slug again. Here’s an entry from the error log; ```auto { "name":"Log", "hostname":"planamag", "pid":19192, "level":50, "req":{ "meta":{ "requestId":"b05edaa6-c174-449f-9e0c-9dce58f4d5a2",

change the slug to something longer but I thought I’d report this bug anyway. - **What version of Ghost are you using?** Ghost-CLI version: 1.14.1 Ghost version: 3.26.1 - How was Ghost installed and
