Bedrock Agent Alias and Version Uses Incorrect Foundation Model

0

I have an existing Bedrock Agent that was originally created against the Claude 2 model. Since then we have released a new alias and version of the agent that uses Claude 3.0. Since Claude 3.5 is now available, we updated the Draft alias and version to use that model. We have completed testing and are happy with the results. However, when I go to create a new alias and version for the agent, they are both created successfully but are pointing at the Claude 3.0 model instead of 3.5.

I have tried creating the new alias and version through both the web console and the CLI. Both results in the same incorrect configuration of the agent.

The foundationModel property of the agent is: "foundationModel": "anthropic.claude-3-5-sonnet-20240620-v1:0"

But the resulting versions are always created with the following: "foundationModel": "anthropic.claude-3-sonnet-20240229-v1:0"

How can I create an alias and version with the correct configuration?

This is now resolved. There was clearly some kind of erroneous data in the agent configuration as originally created by the AWS Console. After changing the foundation model for the working draft to Claude 3.5 v2 for testing and then changing the model back to Clause 3.5 v1, creating a new version and alias for the agent resulted in the correct foundation model being applied.
