I can't run gemini cli with my own docker image, it always loads the default sandbox image

[bitic]

Hi,

I'm using gemini cli 0.34.0 and I added this to my ~/.gemini/settings.json but gemini ignores sandboxImage

  "tools": {
    "sandbox": "docker",
    "sandboxImage": "gemini-custom-sandbox-bitic-v1"
  }

It should find my image.

As a result, gemini is always using sandbox 0.34, instead of my image. Therefore I don't have access to some needed tools.

I also tried setting GEMINI_SANDBOX_IMAGE and it doesn't work.

What can I do? Any ideas? Thanks! :-)
