Dify version

0.15.3

Cloud or Self Hosted

Self Hosted (Source)

Steps to reproduce

Deploy Dify with local source code on two virtual hosts. One host (12.1.1.216) installs Redis, PostgreSQL, Weaviate, and Dify API/Worker Service, while the other host (12.1.1.218) installs Dify Web. After completing the installation according to the official documentation, started the services.

When accessing http://web-server-ip, a normal page is displayed. However, after entering the email, username, and password and confirming, an error is prompted: Setup failed: An error occurred (MissingContentLength) when calling the PutObject operation: Unknown

The API server prompts the following error message:

ERROR [account_service.py:846] e0d02baded Setup account failed, email: mailname@mailserver, name: kenxt

How to deal with this problem?

✔️ Expected Behavior

logined in , work well

❌ Actual Behavior

browser network tab : An HTTP 400 error is displayed: Request URL: http://12.1.1.216:5001/console/api/setup Request Method: POST Status Code: 400 BAD REQUEST Remote Address: 12.1.1.216:5001 Referrer Policy: strict-origin-when-cross-origin

Hey @kenxt! 👋 I'm here to help you with any bugs, questions, or contributions you have for Dify. Let's squash those bugs together!

The error you're encountering, "MissingContentLength," typically occurs when the AWS S3 client requires a content length for the data being uploaded, but it is not provided. This can happen if the data is a stream or a generator that does not have a predefined content length.

To address this issue, you can try the following solutions:

1. Ensure Data Has a Content Length: If the data being uploaded is a stream, make sure it has a defined content length. You can calculate the length of the data before passing it to the put_object method.

2. Modify the save Method: Update the save method in aws_s3_storage.py to include the ContentLength parameter when calling put_object. Here's an example of how you might modify the method:

   def save(self, filename, data):
       content_length = len(data)  # Calculate the content length
       self.client.put_object(Bucket=self.bucket_name, Key=filename, Body=data, ContentLength=content_length)
   

   This modification explicitly sets the content length, which should resolve the "MissingContentLength" error ^[1].

3. Check for Streamed Data: If the data is being streamed, ensure that the stream provides a way to determine its length, or consider buffering the data to calculate its length before uploading.

By implementing these changes, you should be able to resolve the error and proceed with the setup process successfully.

Can you check the oss settings?

botocore.exceptions.ClientError: An error occurred (MissingContentLength) when calling the PutObject operation: Unknown

There is some thing wrong with this config.

I modified the code in aws_s3_storage.py, checked the oss settings, but there are still errors.
