Describe the bug
When running gemini models, I am getting the follow error.

Error processing AI message: TypeError: Cannot convert undefined or null to object\n at Function.keys ()\n at convertSchemaProperty (/workspace/node_modules/@genkit-ai/vertexai/lib/gemini.js:533:12)\n at /workspace/node_modules/@genkit-ai/vertexai/lib/gemini.js:534:31\n at Array.forEach ()\n at convertSchemaProperty (/workspace/node_modules/@genkit-ai/vertexai/lib/gemini.js:533:38)\n at toGeminiTool (/workspace/node_modules/@genkit-ai/vertexai/lib/gemini.js:330:17)\n at Array.map ()\n at /workspace/node_modules/@genkit-ai/vertexai/lib/gemini.js:627:84\n at /workspace/node_modules/@genkit-ai/ai/lib/model.js:290:14\n at /workspace/node_modules/@genkit-ai/core/lib/action.js:204:62 {\n traceId: '54cd40ba57b57c6aa5dd334d7776af0a'\n}",

To Reproduce
I have migrated my project from 0.5 to .9 to 1.0.5; I am getting this error only when I use the gemini model. When I switch to any other model like openAI, there is no error.

** Node version
v18.12.1

Additional context
Working with other models from other community plugins.
