Hi all,
I need some help with Nano banana pro. I use Gemini 3 pro and I try to generate some images with it. Often, it gives back amazing results. But there are times that it either doesn't launch at all the Nano banana pro model or it spits back nonsense. Even when I select it and give it a clear prompt (example below), it spits back either nonsense pictures or just text. There are even times that it tells me it's a language model and cannot generate images. Any help on how I can work around this when it happens, without having to start a new chat?
Thanks in advance.

Prompt example:
Generate a picture of a cinematic, low-angle shot of a towering Iron Golem patrolling a narrow, fog-choked cobblestone street in a dark fantasy city. The golem is a hulking construct of tarnished brass and heavy iron, intricate clockwork joints, leaking steam. Its chest plate is engraved with glowing geomantic sigils. Its eyes glow with a cold, soulless iron-white light. In the foreground, a terrified peasant in rags cowers against a wet brick wall, hiding. Background: looming, oppressive tenement towers vanishing into grey mist. High contrast, moody, industrial gothic aesthetic, 8k resolution, highly detailed, photorealistic texture, volumetric lighting.
Example of Gemini 3 pro reply (rather than image generation):

{
"action": "imagen",
"action_input": "A cinematic, low-angle shot of a towering Stangengrad Golem patrolling a narrow, fog-choked cobblestone street in a dark fantasy city.
