While implementing aws textract using boto3 for python.
Code:
import boto3
# Document
documentName = "/home/niranjan/IdeaProjects/amazon-forecast-samples/notebooks/basic/Tutorial/cert.pdf"
# Read document content
with open(documentName, 'rb') as document:
imageBytes = bytearray(document.read())
print(type(imageBytes))
# Amazon Textract client
textract = boto3.client('textract', region_name='us-west-2')
# Call Amazon Textract
response = textract.detect_document_text(Document={'Bytes': imageBytes})
below are credential and config files of aws
niranjan@niranjan:~$ cat ~/.aws/credentials
[default]
aws_access_key_id=my_access_key_id
aws_secret_access_key=my_secret_access_key
niranjan@niranjan:~$ cat ~/.aws/config
[default]
region=eu-west-1
I am getting this exception:

UnsupportedDocumentException: An error occurred (UnsupportedDocumentException) when calling the DetectDocumentText operation: Request has unsupported document format
I am bit new to AWS textract, any help would be much appreciated.
As DetectDocumentText API of Textract does not support "pdf" type of document, sending pdf you encounter UnsupportedDocumentFormat Exception. Try to send image file instead.
Incase if you still want to send pdf file then you have to use Asynchronous APIs of Textract. E.g. StartDocumentAnalysis API to start analysis and GetDocumentAnalysis to get analyzed document.
Detects text in the input document. Amazon Textract can detect lines of text and the words that make up a line of text. The input document must be an image in JPEG or PNG format. DetectDocumentText returns the detected text in an array of Block objects.
