Dify version

0.14.1

Cloud or Self Hosted

Cloud, Self Hosted (Docker)

Steps to reproduce

1. Create a simple response flow using the Dify cloud service.
2. Enable "Next Step Question Suggestions" in the "Features" section.
3. Ask any question and check the browser's network console, where the returned suggested questions list is empty.

For comparison, I have previously set up two Dify applications locally (both docker deployment). I found that the earlier deployed version (0.13.2) still provides question suggestions after upgrading to the latest version (0.14.1), while the later deployed version behaves the same as the cloud service (both fail to provide question suggestions). In all three test cases, "Next Step Question Suggestions" was enabled in the "Features" section.

Normal working version

Abnormal version

✔️ Expected Behavior

provide some suggested question

❌ Actual Behavior

provides not suggested question

@KroMiose Hello there! I'm Dosu, a bot that can help you solve bugs, answer questions, and become a contributor. I'm here to help you while waiting for a human maintainer.

I found a similar unsolved discussion titled Why the suggested-questions always return empty? ^[1]. This might be related to the issue you're experiencing.

For your specific case, since the issue occurs in both cloud and self-hosted environments with version 0.14.1, but not in the earlier version 0.13.2, it could be related to changes introduced in the newer version. You might want to check the configuration settings related to the 'Next Step Question Suggestions' feature, such as suggestedQuestions and suggestedQuestionsAfterAnswerConfig, to ensure they are correctly set up ^[2].

Additionally, the MessageSuggestedQuestionApi class includes error handling that might log relevant errors if the feature is returning empty results. Checking the logs for any exceptions or errors could provide more insights into the issue ^[3].

I have read the duplicate issues provided by dosu and made sure that the corresponding switch has been turned on on the page. The problem has not been solved. I have also tried it in the latest updated version, and the result is the same.
