There’s no evidence of a code bug in Dify 1.4.3 that would prevent the end node from outputting results. The most common causes for this are: the end node’s output variable selector is misconfigured (for example, it’s not set to the variable actually produced by upstream nodes), the upstream node (like the LLM) isn’t producing the expected variable (such as "text"), or there’s a workflow routing error. Double-check that your end node is configured to output the correct variable (typically ['llm', 'text']), and that the upstream node is actually producing this output. If you’ve made any custom UI changes, those could also affect output propagation. Reviewing logs for errors can help pinpoint where the output is getting lost. If you’re still stuck, try simplifying your chatflow to isolate the problem source.
