the relevant code pieces

agent := NewSupplierContractAgent(ctx, bearerToken)
runner := adk.NewRunner(ctx, adk.RunnerConfig{
		Agent:           agent,
		EnableStreaming: true,
		CheckPointStore: store.NewInMemoryStore(),
	})

	responseSchema := &einoSchema.Schema{}
	ChatModel, err = gemini.NewChatModel(ctx, &gemini.Config{

		ResponseJSONSchema: responseSchema,
		Client:             client,
		Model:              "gemini-3-flash-preview", // or gemini-1.5-pro, etc
		ThinkingConfig: &genai.ThinkingConfig{
			IncludeThoughts: false,
			ThinkingBudget:  nil,
		},
	})

	iter := runner.Run(ctx, []adk.Message{
		{

			Role:    schema.User,
			Content: "what are my contracts ",
		}},
		adk.WithCheckPointID("1"),
		adk.WithToolOptions([]tool.Option{authInput(bearerToken)}),
	)

error:
name: SupplierContractFinder
path: [{SupplierContractFinder}][FATAL] 2026-02-18 10:28:45 index is nil

when enablestreaming is false the code functions properly and my agent calls the tools, but when turned on it returns an index is nil and agent action is nil in the event. Is there any solution to getting gemini tool calls to work properly when enable streaming is true on the runner?
