**Questions?**

Can textract handle signatures and detect them?

At this time Textract appears to treat signatures the same as any other handwriting in a form. It can detect key-value pairs for forms, but the result of turning a signature into text often will have low confidence.

How to handle custom parts.


** Lab Feedback **
lab broken in a couple places.  sudo pip install boto3.  and the last part there is no S3 bucket so prompts to create one but we likely don't have IAM  permissions to do so.


Lab 2: Lambda Console UI impacts/breaks steps for Task 1
Also: Lambda function doesn't have permission to write to CW Logs and awsstudent is missing permissions to view the Cloudwatch Metrics/Logs for Lambda.

Did a work around for running lambda locally with SAM CLI or by executing test event in the lambda console.

** Invoking Lambda CLI **

I used the following: 
https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-invoke.html

1. Create a new file in the workspace called event.json and copy paste the test event into it
2. Edit the file contents so that the bucket name and the key name for one of your sample files is in it (don't include s3:// in front of the bucket name)
3. Run `sam local invoke ComprehendKeyPhraseAnalysis --event event.json` to invoke the lambda locally
