Azure Document AI: Unable to retrieve the bounding region for empty value in KeyValuePairs

Question

Hello,

I am looking to extract key-value pairs from documents using Azure Document AI. In particular, I want to extract the information from the forms with empty values. However, during testing, I observed that no bounding region is returned for the empty value associated with a key, i.e., the empty line after the key.

Is there a way to retrieve the region information for an empty value in addition to the region information for the key? Should I try training a custom model or using a prebuilt-layout?

Thank you,

Rom
