temporarily_
Registry Context
Use this error value when the authorization server cannot complete the request because it is temporarily overloaded or under maintenance.
Technical Summary
`temporarily_unavailable` is one of the registered OAuth 2.0 `error` values used in authorization error responses. It is carried as a single ASCII error code, and its value must satisfy the RFC6749 character restrictions for the `error` parameter.
When Used
In authorization error responses, including authorization code and implicit grant flows, when the server is temporarily unable to handle the request.
Normative Requirements
Authorization servers
RFC 6749 - Section 4.1.2.1
emit `error` parameter values containing characters outside the permitted ASCII set..
Condition: When serializing the `error` parameter for an OAuth 2.0 error response.
Values for the "error" parameter MUST NOT include characters
RFC 6749 - Section 4.1.2.1
include `temporarily_unavailable` as a valid single ASCII `error` code in authorization error responses..
Condition: When generating an authorization error response.
temporarily_unavailable The authorization server is currently unable to handle the request
Validation Guidance
Accept the registry value only if it is exactly `temporarily_unavailable`.
Reject any `error` value that contains characters outside the RFC6749 permitted ASCII range.
Security Notes
RFC 6749 - Section 4.1.2.1
This error indicates temporary server incapacity, so implementations should avoid exposing internal operational detail beyond the standardized code and optional response fields.
