portal_domain_limit_exceeded - Unkey Docs

err:unkey:limits:portal_domain_limit_exceeded

Your workspace already has as many portal domains as it can hold, so portal.createDomain didn’t add another one. You get HTTP 403. Waiting won’t change it.

Example response

{
  "meta": {
    "requestId": "req_2c9a0jf23l4k567"
  },
  "error": {
    "detail": "A workspace can hold at most 10 portal domains. Remove a domain you no longer need, then retry.",
    "status": 403,
    "title": "Forbidden",
    "type": "/errors/unkey/limits/portal_domain_limit_exceeded"
  }
}

How to fix

Remove a portal domain you no longer use with portal.deleteDomain.
Create the domain again.

err:unkey:limits:custom_domain_limit_exceeded: the same limit for custom domains on your apps, which your plan sets.
err:unkey:data:domain_already_exists: the domain is already attached to this workspace.
