Not found — the referenced connector or resource does not exist. Error codes: NOT_FOUND — the referenced connector or resource does not exist for the tenant; NO_ACTIVATION_PROFILE — the tenant has no active activation profile to deploy (only emittable by deployActivationProfile). Not every code applies to every operation — check the individual operation's description.

Unsupported media type — the request body Content-Type is not one this operation accepts, or it was omitted. Send application/json. Error code: UNSUPPORTED_MEDIA_TYPE.

Unprocessable entity. This API returns 422 for both schema-level and business-rule failures. Error codes: VALIDATION_FAILED — malformed JSON, a missing or mistyped required field, or a constraint violation (the field property identifies the offending body field where known); VENDOR_MISMATCH — the body vendor of an updateSyncSettings request does not match the connector's stored vendor; CONNECTOR_NOT_CONNECTED — the connector's credentials are not valid against the UEM platform; CONNECTOR_MISCONFIGURED — the UEM platform rejected the connector configuration.
Note that connector creation can also fail with 400 when the connection test itself fails — see the 400 response on that operation.

Service unavailable — the UEM platform could not be reached or returned an error. Retry later. Error code: UEM_UNAVAILABLE.
