Enum OAuth2Error 

pub enum OAuth2Error {
    InvalidEndpoint(String),
    EndpointStatus(u16),
    MalformedResponse(String),
    Fetch(String),
    MtlsConfig(String),
}

Error acquiring a token (DW-035). All variants surface to the client as 502 oauth2_token_unavailable; the Display text is logged, not sent to the client (the envelope never leaks upstream internals).

Variants

InvalidEndpoint(String)

The token endpoint URL is invalid.

EndpointStatus(u16)

The token endpoint returned a non-2xx status.

MalformedResponse(String)

The token endpoint’s response body could not be parsed as a valid token response (missing access_token, non-string, etc.).

Fetch(String)

A network or HTTP error contacting the token endpoint.

MtlsConfig(String)

The mTLS client certificate could not be loaded.
