Dify version

1.2.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Create a Knowedge
  2. Through API, create a document from text, using hierarchical_model
  3. check the frontend - you will see the text correctly uploaded but with no chunks
curl --location --request POST 'http://localhost/v1/datasets/b2563053-d365-49d3-bfe7-25fa17276266/document/create-by-text' \
--header 'Authorization: Bearer {myKey}' \
--header 'Content-Type: application/json' \
--data-raw '{
  "name": "UN NOME",
  "text": "MOCK DATA\\n\\n\\n\\nMOCK DATA",
  "indexing_technique": "high_quality",
  "doc_form": "hierarchical_model",
  "process_rule": {
    "mode": "custom",
    "rules": {
      "pre_processing_rules": [
        {
          "id": "remove_extra_spaces",
          "enabled": true
        },
        {
          "id": "remove_urls_emails",
          "enabled": false
        }
      ],
      "segmentation": {
        "separator": "\\n\\n\\n\\n",
        "max_tokens": 1500,
        "parent_mode": "paragraph"
      },
      "subchunk_segmentation": {
        "separator": "\\n\\n",
        "max_tokens": 500
      }
    }
  },
  "retrieval_model": {
    "search_method": "hybrid_search",
    "reranking_enable": true,
    "top_k": 3,
    "score_threshold_enabled": false
  },
  "embedding_model": "text-embedding-3-small",
  "embedding_model_provider": "openai"
}'

✔️ Expected Behavior

The text chunks to be created as per my process_rule

❌ Actual Behavior

chunks are not created.
Also, on a DB I initially created by crawling a website through firecrawl I get this error in dify_api container console when in chunking settings I try to click on the top right, to select my document:

Hello @Nobsyde! I'm Dosu, a bot here to help you solve bugs, answer your questions, and assist you on your journey as a contributor. I'm ready to help while you wait for a human maintainer. How can I assist you today?

To address the issue of chunks not being created when using the create-by-text API endpoint with the hierarchical_model, ensure that the process_rule.mode is set to "hierarchical" instead of "custom". The "custom" mode may not support hierarchical segmentation properly, which could lead to the issue of chunks not being created as expected [1][2].

Additionally, make sure that the parent_mode and subchunk_segmentation are correctly placed under the rules object within process_rule. This is crucial for the hierarchical segmentation to function correctly [1][2].

Regarding the KeyError: 'only_main_content', this error typically occurs when the key 'only_main_content' is missing from the website_info_list dictionary. This might be due to an incomplete or incorrect data structure being passed to the function. Ensure that the data structure includes all necessary keys and values, especially when dealing with data from crawled websites [1].

ok, by adding parent_mode and changing to mode: hierarchical the issue seems to be resolved, thank you!
