@AdamMusa thank you that's a lot clearer. As you can see:

06:08:41 web.1 | [{role: "user", parts: [{text: "hello"}]},
06:08:41 web.1 | {role: "user", parts: [{text: "hello"}]},
06:08:41 web.1 | {role: "model", parts: [{text: ""}]},
06:08:41 web.1 | {role: "user", parts: [{text: "Hello"}]},
06:08:41 web.1 | {role: "model", parts: [{text: ""}]},
06:08:41 web.1 | {role: "user", parts: [{text: "Hello my friend"}]},
06:08:41 web.1 | {role: "model", parts: [{text: ""}]},

You have a chat history that has 2 user messages, then an empty model response. That empty model message is why Gemini is complaining.

This is probably caused because of the fact that you visited HomeController#index multiple times. You should not use ask every time you visit a page.

Thank you! It was a mistake when I first created it with the wrong model name. After deleting it, the system now works properly.
Here is the response from gemini
