What it Means:

This error happens when the Bedrock agent’s settings (override configuration) don’t match the model’s default settings.

Step 4: Update the override configuration with all required variables and values.

2. Sync Agent and Model Versions

Step 2: Check the version of the foundation model used with your agent.

Step 3: Compare this with the version supported by your Bedrock agent:

Navigate to the Agents section.

Verify that the agent is using a compatible version of the model.

Step 4: If there is a mismatch, update the agent to use the compatible model version.

3. Validate and Test
