Dify version

1.2.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

curl --location 'http://localhost/v1/messages?user=abc-123&conversation_id=90ca92e3-bde1-4d36-b2ad-ba0745cfb663'
--header 'Authorization: Bearer app-jSbEAGjhXnlJs1LFPTPWzLJa'

I noticed there was an earlier report of similar bug #17438 but closed by @crazywoola as not planned. But as far as I can remember this endpoint exists before 1.0.0 was released and worked properly until I upgrade to 1.2.0 last night.

✔️ Expected Behavior

Attached is a response from another dify deployment [1.0.1, Self Hosted (Docker)]

Thinking... \n嗯...用户让我帮忙写一个SQL查询，从students表中选出年龄大于20的男生。首先，我需要确认表结构，但用户没给，所以得做一些合理假设。通常students表可能有字段如id、name、age、gender之类的。\n\n接下来，用户的需求是年龄大于20且性别为男。性别字段可能用'male'或'男'，或者用1/0之类的数字表示。这里中文环境下可能用'男'，但也要考虑可能用英文。需要明确用户的gender列存储方式，但用户没说明，可能需要用常见的值猜测。\n\n然后，正确的SQL语句应该是SELECT * FROM students WHERE age > 20 AND gender = '男'。不过如果gender是用'male'的话，就得改成'male'。或者可能用性别代码，比如1代表男，这时候条件就是gender = 1。但用户的问题里用的是中文“男生”，所以可能更倾向于性别字段存储的是中文字符。\n\n另外，是否需要考虑大小写或者空格？比如'男 '或者'Male'的不同情况？可能需要用户确认，但作为示例，保持简单，使用'男'比较直接。\n\n还要确保年龄是数值类型，这样age>20才能正确比较。如果age是字符串类型的话就会有问题，但一般年龄都是整数，所以没问题。\n\n最后，是否需要选择特定的字段而不是*？用户没说明，所以用*是合理的，但可能建议选择具体字段更好。不过用户的问题只要求检索出记录，所以没问题。\n\n总结下来，正确的SQL应该是SELECT * FROM students WHERE age > 20 AND gender = '男';。不过需要提醒用户如果性别字段的值不同，可能需要调整条件。\n\n\n<details style="color:gray;background-color: #f8f8f8;padding: 8px;border-radius: 4px;" open> Thinking... \n好的，我来帮您编写这个SQL查询。根据您的需求，需要从students表中筛选出年龄大于20岁且性别为男的学生。以下是实现该需求的标准SQL语句：\n\nsql\nSELECT * \nFROM students \nWHERE age > 20 \n AND gender = '男';\n\n\n代码说明：\n1. *SELECT ：表示选择所有字段，您可以根据需要替换为具体字段名\n2. WHERE条件：\n - age > 20：筛选年龄超过20岁的记录\n - gender = '男'：筛选性别为男的记录（若您的性别字段使用其他表示方式如'male'或1，请相应调整字符串值）\n3. AND逻辑运算符：确保同时满足两个条件\n\n注意事项：\n- 如果gender字段存储的是英文（如male），请将条件改为gender = 'male'\n- 若年龄字段类型为字符串，请先确认存储格式是否为数值类型，否则需要转换\n- 建议在实际使用前先用DESC students确认表结构中的字段名称和类型\n\n需要其他调整请随时告知！",

But as far as I can remember this endpoint exists before 1.0.0 was released and worked properly until I upgrade to 1.2.0 last night. ### ✔️ Expected Behavior Attached is a response from another dify deployment [1.0.1, Self Hosted (Docker)] { "limit": 20, "has_more": false, "data": [ { "id": "09d638a0-ddf2-44a7-8c46-2f3fd10f66da", "conversation_id": "c1cdc535-a2e7-40e4-9383-5c87e95f59b2", "parent_message_id": "00000000-0000-0000-0000-000000000000", "inputs": { "model_name": "deepseek" }, "query": "你擅长编写SQL代码，请结合具体问题编写正确规范的SQL代码，我的问题是：帮我从 students 表中检索出所有年龄大于 20的男生", "answer": "\n<details style=\"color:gray;background-color: #f8f8f8;padding: 8px;border-radius: 4px;\" open> <summary> Thinking... </summary>\n嗯...用户让我帮忙写一个SQL查询，从students表中选出年龄大于20的男生。首先，我需要确认表结构，但用户没给，所以得做一些合理假设。通常students表可能有字段如id、name、age、gender之类的。\n\n接下来，用户的需求是年龄大于20且性别为男。性别字段可能用'male'或'男'，或者用1/0之类的数字表示。这里中文环境下可能用'男'，但也要考虑可能用英文。需要明确用户的gender列存储方式，但用户没说明，可能需要用常见的值猜测。\n\n然后，正确的SQL语句应该是SELECT * FROM students WHERE age > 20 AND gender = '男'。不过如果gender是用'male'的话，就得改成'male'。或者可能用性别代码，比如1代表男，这时候条件就是gender = 1。但用户的问题里用的是中文“男生”，所以可能更倾向于性别字段存储的是中文字符。\n\n另外，是否需要考虑大小写或者空格？比如'男 '或者'Male'的不同情况？可能需要用户确认，但作为示例，保持简单，使用'男'比较直接。\n\n还要确保年龄是数值类型，这样age>20才能正确比较。如果age是字符串类型的话就会有问题，但一般年龄都是整数，所以没问题。\n\n最后，是否需要选择特定的字段而不是*？用户没说明，所以用*是合理的，但可能建议选择具体字段更好。不过用户的问题只要求检索出记录，所以没问题。\n\n总结下来，正确的SQL应该是SELECT * FROM students WHERE age > 20 AND gender = '男';。不过需要提醒用户如果性别字段的值不同，可能需要调整条件。\n</details>\n\n<details style=\"color:gray;background-color: #f8f8f8;padding: 8px;border-radius: 4px;\" open> <summary> Thinking... </summary>\n好的，我来帮您编写这个SQL查询。根据您的需求，需要从students表中筛选出年龄大于20岁且性别为男的学生。以下是实现该需求的标准SQL语句：\n\n```sql\nSELECT * \nFROM students \nWHERE age > 20 \n AND gender = '男';\n```\n\n**代码说明：**\n1. **SELECT ***：表示选择所有字段，您可以根据需要替换为具体字段名\n2. **WHERE条件**：\n - `age > 20`：筛选年龄超过20岁的记录\n - `gender = '男'`：筛选性别为男的记录（若您的性别字段使用其他表示方式如`'male'`或`1`，请相应调整字符串值）\n3. **AND逻辑运算符**：确保同时满足两个条件\n\n**注意事项：**\n- 如果`gender`字段存储的是英文（如`male`），请将条件改为`gender = 'male'`\n- 若年龄字段类型为字符串，请先确认存储格式是否为数值类型，否则需要转换\n- 建议在实际使用前先用`DESC students`确认表结构中的字段名称和类型\n\n需要其他调整请随时告知！", "message_files": [], "feedback": null, "retriever_resources": [], "created_at": 1744194206, "agent_thoughts": [], "status": "normal", "error": null } ] } ### ❌ Actual Behavior Attached is the error log from dify-api-1 2025-04-10 20:02:39 api-1 | 2025-04-10 12:02:39.993 ERROR [Dummy-5] [app.py:875] -

There is a known issue with the /v1/messages endpoint in Dify version 1.2.0, which causes an "Internal server error" due to a bug in that version. This issue affects both cloud and self-hosted installations. A workaround is to use the /v1/chat-messages endpoint, which functions correctly. For further diagnosis in a self-hosted Docker setup, you can check the logs of the 'api' container using the command docker-compose logs api [1].
