Azure Document Intelligence 404 Not found

Question

from langchain_community.document_loaders import AzureAIDocumentIntelligenceLoader

url_path = "https://www.posb.com.sg/Resources/posb/docs/deposit/posb_deposits_guide.pdf"
endpoint = "https://<myendpoint>.cognitiveservices.azure.com/"
key = "<mykey>"
loader = AzureAIDocumentIntelligenceLoader(
    api_endpoint=endpoint, api_key=key, url_path=url_path, api_model="prebuilt-layout"
)

documents = loader.load()

print(documents)

Hi. I'm trying to parse a document using Azure Document Intelligence using the langchain community document loader. When calling loader.load(), it's saying resource 404 not found. Do I need to configure anything extra in my azure platform?

Traceback (most recent call last):

Hi @Elix Chen,

Thank you for reaching out. The 404 Not Found error you're encountering when using the AzureAIDocumentIntelligenceLoader in LangChain typically suggests that the requested resource could not be found. This could be due to an incorrect API endpoint or model name, an inaccessible document URL, or a misconfiguration in your Azure Cognitive Services account. Please double-check that your endpoint URL and API key are correct.

I tried to reproduce the issue with the provided code and was able to successfully extract the document. To ensure proper functionality, please make sure to install the necessary packages correctly. You should first install LangChain and Azure Form Recognizer using the following commands:

pip install langchain
pip install langchain-community azure-ai-formrecognizer

See output:

Also please look into the documentation:

• Azure AI Document Intelligence client library for Python with pip
• Get started with Document Intelligence

I hope this helps. Do let us know if you any further queries.
