Document Intelligence Model Internal Server Error

Question

Document Intelligence Model Internal Server Error

Antony Clarke 0

We are using AP Automation solution and facing issues reading an invoice that is 476 pages and 918 KB.

Azure supports 2000 pages, I also tested on another Document Intelligence instance and had same issue. I then split to first two pages and it processed so PDF should be ok.

Have used both Power Automate action and Postman.

The response only has after about 9 minutes:

{

"status": "failed",

"createdDateTime": "2025-02-20T13:02:26Z",

"lastUpdatedDateTime": "2025-02-20T13:02:26Z",

"error": {

"code": "InternalServerError",

"message": "An unexpected error occurred.",

"details": [

{

"code": "InternalServerError",

"message": "An unexpected error occurred."

}

]

}

Hmm 500 error when trying to edit question.

Just to confirm using:
cognitiveservices.azure.com/documentintelligence/documentModels/prebuilt-invoice:analyze?api-version=2024-11-30&features=keyValuePairs

Also tried without features=keyValuePairs

Hi Antony Clarke,
Greetings & Welcome to the Microsoft Q&A forum! Thank you for sharing your query.
It seems that you are encountering an Internal Server Error while using the Azure Document Intelligence service to process a large invoice document consisting of 476 pages and 918 KB. Despite Azure supporting up to 2000 pages, you are facing issues with this specific document.
The error message you provided indicates that the processing failed due to an unexpected error, resulting in an InternalServerError response. Here are some steps you can take to troubleshoot and potentially resolve this issue:

Sometimes, temporary infrastructure issues can cause this error. Trying again might resolve the problem if the issue was momentary.
While Azure supports up to 2000 pages, the size of the document can also impact processing. Ensure that the document size is within the supported limits for processing.
Verify the status of the Azure Document Intelligence service to ensure there are no ongoing incidents or outages that could be affecting processing.
If possible, review the logs or diagnostic information from the Document Intelligence service to gather more details about the specific error that occurred during processing.

I hope this information helps.
