Textract AnalyzeDocument errors with some pdf files (unsupported document format)

Question

Hi,

i get : 
*botocore.errorfactory.UnsupportedDocumentException: An error occurred (UnsupportedDocumentException) when calling the AnalyzeDocument operation: Request has unsupported document format *

when trying to analyze some pdf files to get tables extracted . My code is executed remotely (from my pc on pycharm) to launch textract on files stored on S3. My program is working with similar pdf with no error:

```
response = textract.analyze_document(
        Document={
            'S3Object':{
                'Bucket': bucket_name,
                'Name':document_name
            }
        },
        FeatureTypes= ["TABLES"])
    doc = Document(response)
```

The file is correctly analyzed using the web interface "try textract" (so i guess it's not corrupted)

Thanks in advance for your help.

Answer

ok i think you should add a control between

```
response = textract.analyze_document(
        Document={
            'S3Object':{
                'Bucket': bucket_name,
                'Name':document_name
            }
        },
        FeatureTypes= ["TABLES"])
```

and

```
    doc = Document(response)
```

in case there is no table extracted from the pdf file

table_blocks = [block for block in response['Blocks'] if block['BlockType'] == 'TABLE']
    
    if not table_blocks:
        print("No tables found in the document.")
    else:
        # process table data here
 doc = Document(response)

Answer

Hi there,

For PDFs, you should use `start_document_analysis`. You can update you code to something similar:

```
response = textract.start_document_analysis(
        DocumentLocation={
            'S3Object':{
                'Bucket': bucket_name,
                'Name':document_name
            }
        },
        FeatureTypes= ["TABLES"])
    doc = Document(response)
```
