providers.invalid_statusprovidersRule R9Unknown provider status
A provider's status is active, maintenance or disabled.
Why the API refuses
WHEN UpdateProvider is executed, THE SYSTEM SHALL apply only the fields present, reject a status other than active, maintenance or disabled, and bump the provider's version.
What to do
Use one of the three. maintenance is the one worth knowing: it keeps the provider registered and routable-last rather than removing it, which is what you want during a planned provider window.
