Dify version

1.13

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Summary

The Dify Agent becomes unresponsive ("hangs") in conversations after using external tools, specifically when attempting to process follow-up questions.

Tool Integration: Various (Perplexity, Tavily)

Severity

High - Blocks further conversation and requires conversation restart
Steps to Reproduce

Start a new conversation with the Dify Agent
Exchange several messages that don't require tool usage
    Expected: Agent responds normally
    Actual: Agent responds normally
Ask a question that requires tool usage (e.g., search request)
    Expected: Agent uses tool and provides answer
    Actual: Agent uses tool and provides answer correctly
Ask a follow-up question to the tool-assisted response
    Expected: Agent processes and responds to follow-up
    Actual: Agent shows typing indicator (three dots) briefly, then clears
Attempt additional questions
    Expected: Agent processes and responds
    Actual: Status shows partial completion (e.g., "2/2", "3/3", or "4/4") with empty response bubble

✔️ Expected Behavior

I can continue prompting as long as I want.

❌ Actual Behavior

Prompts "hang" after a single successful round of using tools

Hey there, @russch! I'm here to help you with any bugs, questions, or contributions. Let's tackle this issue together!

I found a similar unsolved discussion regarding Dify agents timing out due to slow tool responses [1]. This might be related to the issue you're experiencing with the agent hanging after tool usage.

For your specific issue, you might want to check the error handling and timeout mechanisms in place for tool-assisted responses. Dify provides several options, such as setting default values, using fail branches, and configuring error retries, which might help in managing the agent's responsiveness after tool usage [2]. Additionally, you can customize the default timeout settings for tool-assisted responses by modifying the environment variables in the docker/docker-compose.yaml file [3].

These steps might help in addressing the hanging issue you're encountering.

To continue talking to Dosu, mention @dosu.

FYI - I submitted https://github.com/langgenius/dify/issues/17080 shortly after this defect, and it has been resolved-fixed. I'm now finding I can continuously use both Tavilty and Perplexity without the Agent hanging. Can't be 100% sure the errors being thrown by .0.2 and .03 of the Perplexity tool were causing downstream issues in the agent, but there's correlation. Everything is good when I use .0.4 of the Perplexity tool.

If you're interested in keeping this open to understand why the Perplexity tool throwing exceptions might have caused the agent hang, feel free to investigate. But I am unblocked so as far as I'm concerned, this can be closed.

And I tried the Tavily Extract tool (new to me), it failed during the course of answering a prompt, and the very prompt also "hung" - so this isn't limited to Perplexity from what i can see.

Cannot reproduce on my side. It will be helpful if you can provide some background logs.

Any errors when it hangs, can be frontend or backend(plugin daemon)

daemon log is clean - all 200's.

nginx shows some 499s (I've never heard of these before):

I can see It hits the maximum iteration from the screenshot, try to ask Claude do not use tools more than 5 times.

Hi, @russch. I'm Dosu, and I'm helping the Dify team manage their backlog. I'm marking this issue as stale.

Issue Summary:

  • The Dify Agent became unresponsive after using external tools in a self-hosted Docker environment with version 1.13.
  • You resolved the issue by updating the Perplexity tool to version 0.4, but noted similar issues with the Tavily Extract tool.
  • Limiting tool usage to no more than five times was suggested to prevent the agent from hanging.

Next Steps:

  • Please let me know if this issue is still relevant to the latest version of the Dify repository by commenting here.
  • If no updates are provided, this issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!
