Hello,
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 you

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:
You can refer: Azure documentation on Form Recognizer REST API.
I hope you understand. Do let us know if you any further queries.

Hi @Munawar,
Thank you for your follow-up query.
Based on the screenshot you provided, it appears that the table itself is visible on the right side of the labeling pane during the training phase.
Once you have trained your documents, you can test your data and view the extracted table values by clicking on the table symbol, as shown in the screenshot below.
Also, you can try using prebuilt Document Intelligence Invoice model.
Let me know, if you have any further questions. Thank you.
Thank you for your response. Yes, I am successfully retrieving values for individual fields through the API in my application. However, the issue persists with the table data, which continues to return null. Could this be related to how I'm referencing the table in my API requests? Do I need to specify the table name or any other additional parameter to ensure the table data is extracted correctly? Any advice on this would be greatly appreciated.
Hi @Munawar,You're welcome! Based on your follow-up query, it seems like you are still encountering an issue with the table data returning null in the API response, even though you are able to retrieve values for individual fields successfully.
To ensure correct extraction of table data in your API requests, you may need to specify the table name and relevant parameters. Refer to the Azure documentation on Form Recognizer REST API v2.1, specifically the "Analyze Layout" API operation, which requires you to specify the table's bounding box coordinates and header information.
If the issue persists, we recommend raising a support request with Microsoft Azure support for further assistance.
I hope this helps. Thank you.
