Issue with Table Values Returning Null in API Response After Training Custom Extraction Model

Munawar 0 Reputation points


I need a little assistance with an issue I'm encountering using Document Intelligence Studio. I've successfully trained a few invoices with a custom extraction model, and while I'm able to extract all specified fields correctly via the API, I'm facing a problem with the table values—they are returning null. However, during the training phase, these values are displayed perfectly.

Could someone please help me troubleshoot this issue? I've attached a screenshot below for reference, which illustrates the successful training display versus the API response. Any guidance on how to resolve this discrepancy would be greatly appreciated.

Thank you2.jpg

    Hi @Munawar,

    Thank you for reaching out to Microsoft Q&A forum!

    Based on your description, it seems like you were encountering an issue with table values returning null in the API response after training a custom extraction model in Document Intelligence Studio.

    I tried repro the issue and able to extract the table values using the REST API. See the screen shot below:

    To troubleshoot this issue, you can try the following steps:

    1. Check if the table values are correctly labeled in the training data.
    2. Verify that the table values are included in the API call.
    3. Check if the API response includes the table values.

    You can refer: Azure documentation on Form Recognizer REST API.

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