Error message

Unsupported feature: ${feature}

What it means

Thrown by AiFeatureServiceFactory.getAiFeatureService when the Feature enum switch has no matching case. The switch covers TEXT_GENERATE, TEXT_CLASSIFY, TEXT_SUMMARY, TEXT_ENTITY_EXTRACT, IMAGE_CLASSIFY, IMAGE_ENTITY_EXTRACT, IMAGE_CAPTION; any other value (or a future enum constant added without a case) hits the default throw. Code PE-ARG-5000.

Solutions

1. Confirm the requested Feature is one of the seven supported values.
2. If you added a new Feature enum constant, add a corresponding case to the factory switch.
3. Validate the feature value against the supported set before calling the factory.

Example fix

// before: factory has no case for the new constant
//   case UNSENT_FEATURE -> ...
// after: add the case
switch (feature) {
    // ...existing cases...
    case NEW_FEATURE -> { return new NewFeatureServiceImpl(); }
}

// Confirm feature is supported before invoking the factory
Set<Feature> supported = EnumSet.of(
    Feature.TEXT_GENERATE, Feature.TEXT_CLASSIFY, Feature.TEXT_SUMMARY,
    Feature.TEXT_ENTITY_EXTRACT, Feature.IMAGE_CLASSIFY,
    Feature.IMAGE_ENTITY_EXTRACT, Feature.IMAGE_CAPTION);
if (!supported.contains(feature)) {
    return errorResult("Unsupported feature: " + feature);
}

boolean isSupportedFeature(Feature f) {
    return switch (f) {
        case TEXT_GENERATE, TEXT_CLASSIFY, TEXT_SUMMARY, TEXT_ENTITY_EXTRACT,
             IMAGE_CLASSIFY, IMAGE_ENTITY_EXTRACT, IMAGE_CAPTION -> true;
        default -> false;
    };
}

try {
    AiFeatureService svc = AiFeatureServiceFactory.getAiFeatureService(feature);
} catch (AppsmithPluginException e) {
    if (e.getMessage().startsWith("Unsupported feature")) {
        // surface supported feature list to the user
    }
}

When it happens

Trigger: Calling getAiFeatureService with a Feature value not handled by the switch — e.g. null (would NPE in switch instead), or a newly added enum constant the factory wasn't updated to support.

Common situations: A new Feature variant is introduced in the enum but the factory switch is not updated; a caller passes an unexpected/custom feature; deserialization yields an unmapped feature value.
