err:unkey:data:ratelimit_namespace_already_exists
ratelimit.createNamespace named a namespace that already exists or was deleted in your workspace, so it didn’t create one. You get HTTP 409.
Example response

Likely causes

  • You already created this namespace, or ratelimit.limit created it the first time a root key that can create namespaces used the name.
  • A namespace with this name was deleted. A deleted name can’t be reused.

How to fix

  1. Reuse the existing namespace. Find it with ratelimit.listNamespaces.
  2. Or choose another name. Names are case-sensitive, so Email and email are different namespaces.
