My project encountered some errors when running after upgrading from version 3 to version 4 of Gradio

[SunJR24]

Describe the bug

My project initially ran in a graphical environment of=3.30.0, but later upgraded to 4.15 due to the need to add features. After the upgrade, the first step was to run the report error AttributeError: 'Textbox' object has no attribute 'style'. I tried to modify the code, removed the style function, resolved the error, and the webpage graph can be opened normally. But a new problem appeared again. After entering my question in the dialog box, the chatbot's answer was only replied to in the command box, not on the webpage Graph. At the same time, my command to clear the input box in gr.update was only executed once and no longer executed. But the program is running normally without any errors or termination.

Textbook object having no attribute style

Hi @SunJR24 @Bharath-12205425 the style method was deprecated and removed in 4.0. Can you please consult this pinned issue to migrate from 3.x to 4.x:

#6339

If you still are experiencing issues, please provide a minimal repro with correctly formatted code that we can use to help you. As it stands, this issue includes too much code and incorrect formatting making it difficult to parse so I’ll close this issue for now, but can reopen if you please address these points.
