AWS boto3 : UnknownServiceError: Unknown service: 'Bedrock'

[user-preethy]

Describe the feature

I am facing an issue with boto3 module in AWS. I am using boto3 module & running below code in python. Code execution is successful when running locally but fails with UnknownServiceError when executed in AWS Lambda.

bedrock = boto3.client(service_name='bedrock',region_name='us-east-1',endpoint_url='https://invoke-bedrock.us-east-1.amazonaws.com')

After a lot of research, I found that local boto3 version is 1.28.71 and AWS boto3 version is 1.26.90. I tried by adding latest boto3 as layer in lambda function, but its not working. Still showing old version.
Can anyone please help me with this?

Hi @user-preethy thanks for reaching out. Here is a Knowledge Center article to help with troubleshooting this issue: https://repost.aws/knowledge-center/lambda-python-runtime-errors.

You mentioned that you already tried creating a Lambda layer, could you walks us through the steps that you took to do that?

The Bedrock service was introduced in Boto3 1.28.57 and Botocore 1.31.57, and the default Lambda runtimes for Python are currently boto3-1.26.90 botocore-1.29.90 for Python 3.7-3.10 and boto3-1.27.1 botocore-1.30.1 for Python 3.11.

You can confirm which versions your Lambda function is using by adding:

import boto3
import botocore
print(boto3.__version__)
print(botocore.__version__)

Hi @tim-finnigan thanks for the reply.
I created Lambda layer through console. First, created a folder 'boto3' in local and installed boto3(version 1.28.71) using pip command. Zipped folder and uploaded to S3 bucket. Then, created a layer 'boto3' with the object url from S3 and chose runtime python 3.7,3.8,3.9,3.10,3.11. Finally, added layer in the particular lambda function.Runtime of lambda function is python 3.9
I confirmed version of boto3 and botocore in lambda function. It is boto3-1.26.90 botocore-1.29.90.

Hi @user-preethy thanks for following up. Can you confirm that your Lambda layer is attached here?

In the article linked earlier, I recommend following the steps under the section Manually create a Lambda layer that uses the latest Boto3 version which involves using the AWS CLI.

In the Lambda Developer Guide you can find more information on working with Lambda layers and packaging Python dependencies.
