Hello, @glacierck! I'm here to assist you with any bugs, questions, or contributions. Let's work together to resolve the issue you're facing.

The error you're encountering is due to the name parameter being None, which causes a TypeError when the code tries to calculate its length. To resolve this, ensure that the name parameter is provided in your request.

Here's how you can modify your request to include the name parameter:

curl --location --request POST 'https://api.dify.ai/v1/datasets/{dataset_id}/documents/{document_id}/update_by_text' \
--header 'Authorization: Bearer {api_key}' \
--header 'Content-Type: application/json' \
--data-raw '{"text": "text", "name": "your_document_name"}'

Make sure to replace "your_document_name" with the actual name you want to use for the document. This should prevent the NoneType error [1].

To continue talking to Dosu, mention @dosu.

hi @dosu。The parameter 'name' should be optional and described as such in the document, and it should also be the same in practical applications!

I have confirmed this exception twice and checked the source code of the interface to confirm the existence of the bug.

Hi, @glacierck. I'm Dosu, and I'm helping the Dify team manage their backlog. I'm marking this issue as stale.

Issue Summary:

  • A bug in Dify API (version 0.9.1) requires the 'name' parameter, which should be optional.
  • You confirmed the bug by checking the source code.
  • I suggested including the 'name' parameter to avoid errors.
  • @WThirteen recommended testing with Postman or Apifox, but you have already verified the issue.

Next Steps:

  • Please confirm if this issue is still relevant to the latest version of the Dify repository by commenting here.
  • If there is no further activity, this issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!
