    InvalidS3ObjectException: An error occurred (InvalidS3ObjectException) when calling the DetectDocumentText operation: Unable to get object metadata from S3. Check object key, region and/or access permissions.

Answer

I think the problem is that you're rewriting the filename (object name) to have _s in place of spaces. When you do this, the name you're passing to detect_document_text() is no longer the name of the object in the bucket, which is why it can't find it.

If you remove this line, it should work:

filename = '_'.join(file.split(' '))

If you remove this line, it should work:

```
filename = '_'.join(file.split(' '))
```
