Troubleshooting Rekognition Video

The following covers troubleshooting information for working with Rekognition Video and stored videos.

I never receive the completion status that's sent to the Amazon SNS topic

Rekognition Video publishes status information to an Amazon SNS topic when video analysis completes. Typically, you get the completion status message by subscribing to the topic with an Amazon SQS queue or Lambda function. To help your investigation, subscribe to the Amazon SNS topic by email so you receive the messages that are sent to your Amazon SNS topic in your email inbox. For more information, see Subscribe to a Topic.

If you don't receive the message in your application, consider the following:

  • Verify that the analysis has completed. Check the JobStatus value in the Get operation response (GetLabelDetection, for example). If the value is IN_PROGRESS, the analysis isn't complete, and the completion status hasn't yet been published to the Amazon SNS topic.

  • Verify that you have an IAM service role that gives Rekognition Video permissions to publish to your Amazon SNS topics. For more information, see Configuring Rekognition Video.

  • Confirm that the IAM service role that you're using can publish to the Amazon SNS topic by using role credentials. Use the following steps:

    • Get the user Amazon Resource Name (ARN):

      aws sts get-caller-identity --profile RekognitionUser
    • Add the user ARN to the role trust relationship by using the AWS Management Console. For example:

      { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "", "AWS": "arn:User ARN" }, "Action": "sts:AssumeRole", "Condition": {} } ] }
    • Assume the role: aws sts assume-role --role-arn arn:Role ARN --role-session-name SessionName --profile RekognitionUser

    • Publish to the Amazon SNS topic: aws sns publish --topic-arn arn:Topic ARN --message "Hello World!" --region us-east-1 --profile RekognitionUser

    If the AWS CLI command works, you receive the message (in your email inbox, if you've subscribed to the topic by email). If you don't receive the message:

    • Check that you've configured Rekognition Video. For more information, see Configuring Rekognition Video.

    • Check the other tips for this troubleshooting question.

  • Check that you're using the correct Amazon SNS topic:

  • If you subscribe an Amazon SQS queue to your Amazon SNS topic, confirm that your Amazon SNS topic has permissions to send messages to the Amazon SQS queue. For more information, see Give permission to the Amazon SNS topic to send messages to the Amazon SQS queue.
