Error when using Gemini models

I'm getting this error when using Gemini models (flash or pro) with droid (factory CLI):
```
Error: 500 Invalid JSON payload received. Unexpected token.
   esponse":{"result":[main ab7e1ea] feat: 
                       ^
```
I know there is another issue related to Gemini models, but I believe this is a different error.
I'm using the recommended model config.
