Error code

Id already taken

The id you chose already names a type, trait, or asset, or an entry of another type on this branch. Two requests creating the same thing at once can also meet it.

Code: ID_TAKEN
Management API: 400

What to do

Leave the id out so Coho chooses one, or choose another. After a race, send the request again.

The response

Every refusal is an application/problem+json document. Its detail says what went wrong in that request; its type is this page.
