NOT_CUSTOM_MODEL

Error message

BusinessException(ResponseEnum.NOT_CUSTOM_MODEL)

What it means

LLMService.selfModelConfig only supports custom (self-hosted) models, identified by llmSource == 0. Any other llmSource (built-in/platform models) throws BusinessException(NOT_CUSTOM_MODEL) because per-instance config editing is only meaningful for user-defined models.

Solutions

1. Verify the llmSource value sent by the caller; only 0 (custom model) is supported
2. In the frontend, only offer the self-model-config UI for custom models
3. Check for enum drift between client and server llmSource constants
4. Return a clearer client-side message before calling the API when the model is not custom

Example fix

// before
llmService.selfModelConfig(modelId, llmSource); // llmSource may be 1 for built-in
// after
if (llmSource == 0) {
    llmService.selfModelConfig(modelId, llmSource);
} else {
    throw new IllegalArgumentException("self model config requires a custom model (llmSource=0)");
}

if (llmSource == null || llmSource != 0) {
    throw new IllegalArgumentException("selfModelConfig requires llmSource == 0 (custom model), got: " + llmSource);
}

boolean isCustomModel(Integer llmSource) { return llmSource != null && llmSource == 0; }

try {
    Object cfg = llmService.selfModelConfig(id, llmSource);
} catch (BusinessException e) {
    // NOT_CUSTOM_MODEL: redirect user to built-in model config instead
}

When it happens

Trigger: Calling selfModelConfig(id, llmSource) with llmSource != 0, e.g. a frontend sending the source code of a built-in model or omitting/altering the llmSource parameter when requesting self-model config for a model instance.

Common situations: Frontend bug sending wrong llmSource; caller invoking the self-model config endpoint for a built-in marketplace model; enum values changed between frontend/backend versions.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
