Amazon Textract

Hello, 

I am using version 3.0.0 and have some issues using "Analyze Multipage Document" activity. It always return me the following error. Does anyone has any solutions? Thanks!

Here's the error:

Analyze Multipage Document: Cannot find column 5.

RemoteException wrapping System.IndexOutOfRangeException: Cannot find column 5.

is it possible to get the raw text word and line text from the document instead of Key Value Pairs, and Table Data?

Hey UiPAth Team,

Thanks for including the VPC Endpoint as an option. 

However, when I try to use only setting the VPC Endpoint it still asks me for the "Access Key Id" and the "Secret Key".

As this is internal VPC Connection is there any chance to make those not mandatory in case the VPC Endpoint is defined?

As clarification, our VPC admin does not allow us to create IAM users but only assign policys to instance.

Hi Team,

I was wondering if we will have ability to change the API end point to private endpoint rather than pulblic end point

Hi Team,

I am unable Uipath AWS Textract activity 2.1.0 and followed the steps given for IAM user and successfully generated client id and secret on AWS. It gives me following error. Can anyone help

• Thanks. Yes I saw your response. The Request Syntax has the key named "FeatureTypes": [ "string" ], which can have value TABLE | FORMS  The caller needs to call it with either TABLE or FORMS or both
• Let me know if I can have a quick update on the customer activity for just this AnalyzeDocument https://docs.aws.amazon.com/textract/latest/dg/API_AnalyzeDocument.html

I need to only use the table extraction service and not the form extraction service since they both have different pricing on AWS. Is there a way we can differentiate this? Thanks

Hi,

We are working on implementing a Invoice processing flow using Amazon Textract within Uipath. We are taking the asynchronous approach. It is erroring out at the "Get Document Analysis" stage with below message -

Get Document Analysis: A value of type 'UiPath.Amazon.Textract.Client.Models.PageDetailCollection' cannot be set to the location with name 'Pages' because it is a location of type 'UiPath.Amazon.Textract.Client.Models.PageDetail[]'.

Now the Get Document Analysis output by default creates a variable with Type "PageDetail[]" and not "PageDetailCollection" (this is the output of Analyze Multiple Documents stage but we are not using that).

Request your assistance in resolving this issue.

Regards

Doesn't work with PDF?  Amazon Textract does support PDF, but I get an error from this service saying "Invalid Document Type".  Can you update this package, or is there a code repo somewhere where we clone and can update ourselves?

Hello,

I'm running into some issues working with this package (v.2.0.0).

1. Using the "Analyze Multipage Document" activity, I manage to execute a full flow, however the results obtained in the output variable of type "PageDetailCollection" seems to contain no meaningful data. Here's the result of a ".RawJson" on this output variable:

{"Blocks":[], "DocumentMetadata": { "Pages": 1} }

2. I've tried using the series of activities: "Start Document Analysis", "Get Document Analysis Status" and "Get Document Analysis" to do the same thing. The first activity did generate an AWS job. I checked the results of the Job outside of UiPath and it was indeed a successful Textract job. However, it seems that the result of "Get Document Analysis" does not have the type expected by the activity:

Get Document Analysis: A value of type 'UiPath.Amazon.Textract.Client.Models.PageDetailCollection' cannot be set to the location with name 'Pages' because it is a location of type 'UiPath.Amazon.Textract.Client.Models.PageDetail[]'.

3. Both "Get Document Analysis" and "Analyze Multipage Document" throw the following error when the "DiscoverColumnHeaders" flag is active:

Get Document Analysis: Cannot find column 0.

Please note that the document analysis works on the given document when done from a local script using AWS client libraries. This points towards an issue with the UiPath activies. Any help or suggestion would be highly appreciated.
