Can't use same tool in OpenAI & GoogleAI

[temamagic]

I was trying to use same tool for different models, here my tries:

var Tool = llms.Tool{
	Type: tools.ToolTypeFunction,
	Function: &llms.FunctionDefinition{
		Name:        tools.ICal,
		Description: "Send an iCal file to the chat",
		Parameters: map[string]any{
			"type": string(jsonschema.Object),
			"properties": map[string]any{
				"contents": map[string]any{
					"type":        string(jsonschema.String),
					"description": "Contents of the iCal file",
				},
				"file_name": map[string]any{
					"type":        string(jsonschema.String),
					"description": "Name of the iCal file (with .ics extension)",
				},
			},
			"required": []string{"contents", "file_name"},
		},
	},
}

var Tool = llms.Tool{
	Type: tools.ToolTypeFunction,
	Function: &llms.FunctionDefinition{
		Name:        tools.ICal,
		Description: "Send an iCal file to the chat",
		Parameters: jsonschema.Definition{
			Type: jsonschema.Object,
			Properties: map[string]jsonschema.Definition{
				"contents": {
					Type:        jsonschema.String,
					Description: "Contents of the iCal file",
				},
				"file_name": {
					Type:        jsonschema.String,
					Description: "Name of the iCal file (with .ics extension)",
				},
			},
			Required: []string{"contents", "file_name"},
		},
	},
}

tools.ToolTypeFunction - my const "function"

I think we can handle here

langchaingo/llms/googleai/googleai.go

Line 391 in 71ded3c

params, ok := tool.Function.Parameters.(map[string]any)

Or why we have jsonschema.Definition?

I'll try to figure how i can use same models but still no success

or catch errors like

[ {
  "error" : {
    "code" : 400,
    "message" : "* GenerateContentRequest.tools[7].function_declarations[0].parameters.properties[options].items: missing field.\n",
    "status" : "INVALID_ARGUMENT"
  }
} ]

or

[ {
  "error" : {
    "code" : 400,
    "message" : "* GenerateContentRequest.tools[2].function_declarations[0].parameters.type: must be specified when not using one_of\n* GenerateContentRequest.tools[7].function_declarations[0].parameters.properties[options].items: missing field.\n* GenerateContentRequest.tools[13].function_declarations[0].parameters.type: must be specified when not using one_of\n* GenerateContentRequest.tools[15].function_declarations[0].parameters.type: must be specified when not using one_of\n",
    "status" : "INVALID_ARGUMENT"
  }
} ]

What i'm doing wrong?
