Amazon Textract Asynchronous Operations pdf S3Bucket

[AminPatel1]

Hi everyone,

I am using AWS TextractVBORelease_v1.0-062020.bpskill file from DX in Blue Prism.

After setting up a S3 Bucket in AWS Storage, i passed a pdf input for StartDocumentTextDetection page in AWS Textract business object. Now at AnalyzeDocument stage got the Error Code 400 like this:

Can someone kindly help me with this issue. Thank you in advance.

Hi Amin,

I am guessing the error relates to AWS signature. Also noticed that the page "StartDocumentTextDetection" is internal(unpublished) and is used in page "Start Async Processing".  You might want to use the page "Start Async Processing" directly so that you can pass the below required parameters.

What kind of data are you trying to extract from pdf?

Hi Gustavo,

If you could post a screenshot of the parameters passed, that would help to debug.

Hi Shashank,

I have found that this issue occurs because 'AWSCrendentials' were not accessible at 'Get Credentials' stage in page "StartDocumentTextDetection" to update AccessID and SecretKey parameters to generate AWS signature.

So i skipped 'Get Credentials' stage in all pages like "StartDocumentTextDetection" and manually updated AccessID, SecretKey in 'AWS Textract Basic' business object.

Thanks.

Hi Gustavo,

I have found that this issue occurs because 'AWSCrendentials' were not accessible at 'Get Credentials' stage (updates AccessID and SecretKey parameters to generate AWS signature) in all pages of 'AWS Textract Basic' business object.

So as a workaround just skip 'Get Credentials' stage in all pages and manually update AccessID, SecretKey on Initialise page in 'AWS Textract Basic' business object.

Hope this helps.
