Is there any missing content in the 30-minute quick start tutorial?

I have deployed the Dify platform locally and followed the 30-minute quick start tutorial at https://docs.dify.ai/zh/use-dify/getting-started/quick-start exactly today. However, during the test run, an error occurred at the “Integrate Information” node, with the following error message:

Failed to invoke model qwen3-vl-plus, status code: 400, message: <400> InternalError.Algo.InvalidParameter: The input messages do not contain elements with the role of user, request_id: fb5de509-1457-4c4d-9eae-2387856fc0ed

One node in the workflow encountered an exception; please go to the trace to view the logs.

After checking, I am using the qwen3-vl-plus model. Could this be due to the model I am using?

After adjustment, the final running result is as shown in the figure above: only a mobile phone icon is displayed, without any text information. It is hoped that this beginner tutorial could include some explanations of the testing process and expected results, so that newcomers can have an intuitive comparison to determine whether their operations were successful or where adjustments are needed.
