Today, I tried using a new feature from AWS—Amazon Nova Model—to generate videos. However, when integrating it with AWS Lambda using Boto3 SDK, I encountered an error related to the method start_async_invoke. The error message stated that the object has no attribute "start_async_invoke", and I wasn’t sure why exactly this happened.
After some investigation, I suspected that when AWS releases a new feature, it sometimes takes a little time for Lambda runtime environments to update accordingly. As a result, I ran into this issue because my Lambda function was using an outdated version of Boto3.
The solution? Upgrading the Boto3 layer to the latest version! After applying the update, I was able to use the method successfully to generate videos using a provided prompt.
If you're facing the same issue, here’s the exact process you can follow to update your Boto3 layer in AWS Lambda 😊:
Step-by-Step Guide to Upgrading Boto3 in AWS Lambda
1. Open AWS Cloud Shell on the AWS Management Console
2. Create a library directory
Run the following command to create a new directory for your custom Boto3 layer:
LIB_DIR=boto3-mylayer/python
mkdir -p $LIB_DIR
3. Install the latest Boto3 version in the library directory
pip3 install boto3 -t $LIB_DIR
4. Package the dependencies into a ZIP file
Navigate into the boto3-mylayer directory and create a ZIP file containing the updated Boto3 package:
cd boto3-mylayer
zip -r /tmp/boto3-mylayer.zip .
5. Publish the updated layer to AWS Lambda
Run this command to publish the new Lambda layer:
aws lambda publish-layer-version --layer-name boto3-mylayer --zip-file fileb:///tmp/boto3-mylayer.zip
Once this step is completed, AWS will return a confirmation dictionary that includes the ARN (Amazon Resource Name) for the new layer like in the below image. You’ll need this ARN for the final step.
6. Update your Lambda function to use the new Boto3 layer
Replace MY_FUNCTION with your actual Lambda function name and LAYER_ARN with the ARN you obtained in the previous step:
aws lambda update-function-configuration --function-name MY_FUNCTION --layers LAYER_ARN
Example (Replacing MY_FUNCTION & LAYER_ARN):
aws lambda update-function-configuration --function-name genVideoAI --layers arn:aws:lambda:us-east-1:123456789:layer:boto3-mylayer:1
7. Test Your Lambda Function
Now, go back to your AWS Lambda function and test it out. If everything is set up correctly, your function should work without the previous error!
That’s it! This method worked for me, and I hope it works for you as well. Let me know in the comments if this helped or if you faced any issues. Thanks for reading, and happy coding! 🚀
Fact: This is a video model Amazon Nova generated for me after troubleshoot method "start_async_invoke"
