Textract Request has unsupported document format

Hi,

I'm trying to run textract API on a document but it's returning an error: botocore.errorfactory.UnsupportedDocumentException: An error occurred (UnsupportedDocumentException) when calling the AnalyzeDocument operation: Request has unsupported document format

The thing is the document extraction works fine when uploaded to the Textract Console. Also, other documents that my code is looping through work fine as well.

I've checked: The format. It's a .pdf and it worked on the condole. The size. It's only 217KB Pages. Only 7 Open. Nope I dont have the file open somewhere else. It does not appear to be corrupted or encrypted. Regions. I've checked my bucket and textract regions, they're the same and it works on other documents.

I'd say this issue effects about 60% of the documents I'm trying to read.

Any help would be appreciated.

Thank you.
