# Bug: The original conversation suddenly has no response

Due to Google Gemini server modifications this morning, the Golang official package hasn't been updated in time. (https://github.com/google/generative-ai-go/issues/97)

This has caused the LINE Bot examples in my BwAI workshop, National Chengchi University and Taipei University courses to potentially fail to receive responses.

Although the official team is working on resolving the issue, this article will share how to bypass the problem using an alternative method.

### Situation:

Text questions are sent, but there is no response. However, sending photos can be answered correctly. Checking the log shows the error message "unknown field `usageMetadata`".

## Solution:

Please remember to update the latest version of the code to your cloud function and replace function.go, then redeploy.

# Serious Discussion

According to [issue 97](https://github.com/google/generative-ai-go/issues/97), the main problem lies in the information processing part returned by SendMessage.

func main() {
ctx := context.Background()
client, err := genai.NewClient(ctx, option.WithAPIKey(os.Getenv("GEMINI_API_KEY")))
if err != nil {
log.Fatal(err)
}
defer client.Close()
model := client.GenerativeModel("gemini-1.0-pro")
cs := model.StartChat()

msg := "hello"
fmt.Printf("== Me: %s\n== Model:\n", msg)
_, err = cs.SendMessage(ctx, genai.Text(msg))
if err != nil {
    log.Fatal(err)
}

}

## Workaround

You can consider replacing `StartChat()` with the original `model.GenerateContent(ctx, genai.Text(text))`, but you won't be able to use `cs.History = Memory`. At this time, you can use

totalString := fmt.Sprintf("Memory:(%s), %s", string(jsonStr), req)
res, err := model.GenerateContent(ctx, genai.Text(totalString))
if err != nil {
log.Fatal(err)
}

Treat the previous discussion data as `Memory` and put it into the prompt. This is a way to handle it. Later, I found that the results were quite good.
