AWS textract-trp package issue - cannot extract key-value pair

Question

I'm using AWS Lambda running on Python 3.8 to run this code example below:

import boto3
from trp import Document

# Document
documentName = "employmentapp.png"

# Amazon Textract client
textract = boto3.client('textract')

# Call Amazon Textract
with open(documentName, "rb") as document:
    response = textract.analyze_document(
        Document={
            'Bytes': document.read(),
        },
        FeatureTypes=["FORMS"])

#print(response)

doc = Document(response)

for page in doc.pages:
    # Print fields
    print("Fields:")
    for field in page.form.fields:
        print("Key: {}, Value: {}".format(field.key, field.value))

    # Get field by key
    print("\nGet Field by Key:")
    key = "Phone Number:"
    field = page.form.getFieldByKey(key)
    if(field):
        print("Key: {}, Value: {}".format(field.key, field.value))

    # Search fields by key
    print("\nSearch Fields:")
    key = "address"
    fields = page.form.searchFieldsByKey(key)
    for field in fields:
        print("Key: {}, Value: {}".format(field.key, field.value))

Im getting this error

Traceback (most recent call last):

    if(blockMap[cid]["BlockType"] == "WORD"):
KeyError: '73d47382-4f5a-4423-9665-124380736c2a'

Can someone please assist here? I want to extract key-value pairs from PDF invoices without killing myself using REGEX.

• I've added textract-trp package using AWS Lambda layers.
• The same error occurs when I'm running this code locally.

Thanks in advance!
