Dify version

1.3.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

None of the models are able to provide streaming output. In addition, compared to version 0.15.5, the consumption tracking feature is no longer available, and clicking the log icon does not respond either.

The above are some screen recordings related to version 1.3.0. Streaming output is not available, consumption tracking is missing, and clicking the log icon does not produce any response.

This is a screen recording from version 0.15.5. As you can see, streaming output is available, consumption tracking is present, and the log icon is also functional.

These issues have existed for several versions since 1.0.0 and have a significant impact on the user experience. Could you please look into and resolve these problems? Thank you very much.

@dosubot[bot] commented on GitHub (May 14, 2025):

There is a known issue with streaming output in Dify, specifically with workflows that include conditional branches, which are unable to stream output. This is confirmed to be expected behavior by the project maintainers [1]. However, there is no specific information available about issues related to consumption tracking and logging in the documentation.

For streaming output in version 1.3.0, the expected behavior is that when the stream parameter is set to True, the output should be returned in a streaming manner as a Generator[[LLMResultChunk](#LLMResultChunk)]. If streaming is not enabled, the output should be returned as a [LLMResult](#LLMResult). The default setting for the stream parameter is True, indicating that streaming is the standard behavior unless explicitly disabled [2][3][4].

Unfortunately, I couldn't find specific information on changes to consumption tracking and logging features between versions 0.15.5 and 1.3.0. You might want to check the repository's changelog or release notes for detailed updates on these features.
