[Bug] glm-4v图像理解在传json情况下生成乱码

### Checklist

- [ ] 1. I have searched related issues but cannot get the expected help.
- [ ] 2. The bug has not been fixed in the latest version.
- [ ] 3. Please note that if the bug-related issue you submitted lacks corresponding environment info and a minimal reproducible demo, it will be challenging for us to reproduce and resolve the issue, reducing the likelihood of receiving feedback.

### Describe the bug

用加模板的方式启用：
lmdeploy serve api_server --eager-mode /home/nfs/appnfs/sxh/pre_models/ZhipuAI/glm-4v-9b --backend pytorch --model-name glm-4v-9b --device ascend --tp 2 --chat-template /opt/lmdeploy/chat_template/glm-4v.json --server-name 0.0.0.0 --server-port 50055
生成为空或乱码

过程以及错误结果如下：
curl "http://192.168.1.49:50055/v1/chat/completions" -H "Content-Type: application/json" -d '{
"model": "glm-4v-9b",
"messages": [
{
"role": "user",
"content": [
{ "type": "text", "text": "描述这张图片"},

],
"max_tokens": 128,

}'

{"id":"1","object":"chat.completion","created":1734435379,"model":"glm-4v-9b","choices":[{"index":0,"message":{"role":"assistant","content":"(preview) is a pattern","tool_calls":null},"logprobs":null,"finish_reason":"stop"}],"usage":{"prompt_tokens":1647,"total_tokens":1653,"completion_tokens":6}}

内容有时候还会生成：“，，，，，，）））））））），，，，，”类似这种不正常的输出

不加模板启动生成是正常的，但是如果我用k8s调用的话必须要求传模板

我的json模板如下：
{
"model_name": "glm-4v-9b",
"system": "<|vision_start|>system\n",
"meta_instruction": "你是一个名为 GLM-4 的人工智能助手。你是基于智谱AI训练的语言模型 GLM-4 模型开发的，你的任务是针对用户的问题和要求提供适当的答复和支持。",
"eosys": "<|vision_end|>\n",
"user": "<|vision_start|>user\n",
"eoh": "<|vision_end|>\n",
"assistant": "<|vision_start|>assistant\n",
"eoa": "<|vision_end|>",
"separator": "\n",
"capability": "chat",
"stop_words": ["<|vision_end|>"]
}

### Reproduction

lmdeploy serve api_server \
--eager-mode /home/nfs/appnfs/xxx/pre_models/ZhipuAI/glm-4v-9b \
--backend pytorch \
--model-name glm-4v-9b \
--device ascend \
--tp 2 \
--chat-template /opt/lmdeploy/chat_template/glm-4v.json \
--server-name 0.0.0.0 \
--server-port 50055
