tenant_requiredplatformA tenant context is required
Returned by the implementation; no specification rule declares it yet.
The operation needs to know which tenant it acts on and the request did not say. On the platform surface the tenant comes from the path (/tenants/{tenant_id}/…); on the partner surface it comes from the API key.
Why the API refuses
a tenant context is required
What to do
Call the platform form with the tenant in the path, or use a key that belongs to a tenant.
