This requires the multi-tenant plugin with at least one tenant-enabled collection.\n\nReads and direct edits to an existing target-tenant document were not bypassed.\n\nYou are affected if:\n- You are using @payloadcms/plugin-multi-tenant\n\n### Patches\nUsers should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.\n\n### Workarounds\nYou can add access control with `accessResultOverride` on the multi-tenant collection config to ensure a user has access to the tenant before creating.","categories":["Libraries &
