Unsupported auth type: %s

Error message

Unsupported auth type: %s

What it means

HTTP 400 (BadRequestException). Thrown by OpenApiOperatorResolver.resolve when UserIdentityContextHolder.getAuthType() is not USER, USER_TOKEN, or CONSUMER (e.g. ANONYMOUS, null, or an unrecognized value). The resolver cannot determine how to obtain the operator. Same root cause as errors 85/93, centralized in the shared resolver.

Solutions

  1. Authenticate with a supported mechanism (portal SSO -> USER, user-token -> USER_TOKEN, OpenAPI token -> CONSUMER).
  2. Fix the security filter chain to set authType for every authenticated request.
  3. Reject anonymous/unknown authType before reaching the controller.
  4. Ensure the constant matches exactly 'USER'/'USER_TOKEN'/'CONSUMER'.

Example fix

// before: authType = ANONYMOUS -> 400
resolver.resolve("alice");

// after: authenticate as CONSUMER
client.withConsumerToken(token).someWrite(operator="alice");
Defensive patterns

Strategy: validation

Validate before calling

// Ensure a recognized auth type before resolving the operator.
String authType = UserIdentityContextHolder.getAuthType();
if (!Set.of("USER","USER_TOKEN","CONSUMER").contains(authType)) { /* authenticate */ }

Type guard

null

Try / catch

try {
  client.someWrite(appId, payload);
} catch (HttpClientErrorException.BadRequest e) {
  if (e.getResponseBodyAsString().contains("Unsupported auth type")) {
    // authenticate with a supported mechanism and retry
  }
}

Prevention

When it happens

Trigger: Any OpenAPI write endpoint delegating to OpenApiOperatorResolver when the request authenticated as ANONYMOUS or authType was never set in the security context.

Common situations: Endpoint left open to anonymous; security filter failed to populate UserIdentityContextHolder.authType; a new auth mechanism introduced without registering its constant; tests invoking the resolver without a context.
