Gemini flash 3 preview not supported? Consistent run error: 400 status code (no body) and getting ? for token usage.

Description

I am consistently getting these errors in openclaw TUI with gemini flash 3 preview as the provider:
run error: 400 status code (no body)
connected | error
agent main | session main (openclaw-tui) | inference/gemini-3-flash-preview | tokens ?/131k

After repeatedly sending the message a few times it gets through and I get a response from the agent.

Is gemini 3 flash not supported? Or is nemoclaw just expected to be this broken?

Reproduction Steps

run nemoclaw onboard
select google as a provider 6
select gemini flash 3 preview as the model
run openshell sandbox connect

openclaw tui

start sending messages to the agent.

Environment

• OS: Ubuntu 24.04
  -Node.js v22.22.2
  Docker version 28.2.2
  -NemoClaw v0.0.6 and v0.0.10

I used curl and followed the install steps and added a gemini api key, a brave search engine api key, and allowed the default access for pypi, brave, and npm.
