ConsumerApp not exist

Error message

ConsumerApp not exist

What it means

Thrown by ConsumerService.deleteConsumer when no Consumer record is found for the given appId. The method queries consumerRepository.findByAppId(appId). This is used to remove an OpenAPI consumer application and all its associated roles and tokens. If the appId does not correspond to any registered consumer app, deletion cannot proceed. Results in HTTP 400.

Solutions

1. Verify the appId exists as a Consumer record via consumerRepository.findByAppId(appId) before calling deleteConsumer.
2. Check whether the consumer was already deleted (idempotent delete handling).
3. Ensure you are using the consumer app's own appId, not a target Apollo application's appId.

Example fix

// before
consumerService.deleteConsumer(appId);

// after
Consumer existing = consumerRepository.findByAppId(appId);
if (existing == null) {
    // already deleted or never existed — treat as no-op or return 404
    return;
}
consumerService.deleteConsumer(appId);

// Check consumer existence before deletion (idempotent delete)
Consumer existing = consumerRepository.findByAppId(appId);
if (existing == null) {
    log.info("Consumer app {} not found, treating delete as no-op", appId);
    return;
}
consumerService.deleteConsumer(appId);

try {
    consumerService.deleteConsumer(appId);
} catch (BadRequestException e) {
    if ("ConsumerApp not exist".equals(e.getMessage())) {
        // Idempotent: already deleted, no action needed
        return;
    }
    throw e;
}

When it happens

Trigger: Calling deleteConsumer(appId) with an appId that was never registered as a consumer app, has already been deleted, or is an actual Apollo application appId rather than a consumer-app appId.

Common situations: Attempting to delete a consumer app that was already removed in a previous operation. Confusing the consumer-app appId with a regular Apollo application appId. The consumer record was manually deleted from the DB, leaving stale references elsewhere.
