WoW: Getting "Character not found" characters found in the guild-api

I query the guild-api get the members and then gets all the character info from the character-api. The problem is that i get some {'status': 'nok', 'reason': 'Character not found.'} However these characters shows up when you search them on the public website (https://worldofwarcraft.com/en-gb/character/eu/<realm>/<name>).
I would think that the cause is WoW Community API Migration Deadline Extension, but why is then the only place hiding the data the community api. It would make more sence if they where hidden from the public website as well as hidden from the guild members api.

Is this as intended?

Can anyone even confirm that this is only hidden from the community character api. Can give examples to links that show up in all but the character apis, though not my characters.
