Reproduction Steps

// This works
await this.bedrockClient.send(new InvokeInlineAgentCommand({
    foundationModel: "anthropic.claude-3-5-sonnet-20241022-v2:0",
    instruction: "Translate the user input text to Spanish. Only do that, noting more.",
    actionGroups: [
        {
            actionGroupName: "profile-management",
            description: "Functions to manage user profiles including loading and saving profile information.",
            actionGroupExecutor: {
                customControl: "RETURN_CONTROL"
            },
            functionSchema: {
                functions: [
                    {
                        name: "save_profile",
                        description: "Save or update the user's profile",
                        parameters: {
                            name: { type: "string", "required": true }, // <-- Required is explicitely set
                        },
                    }
                ]
            }
        }],
    inputText: "Bonjour",
    // (Other arguments ommited for clarity...)
}));

// This doesn't work
await this.bedrockClient.send(new InvokeInlineAgentCommand({
    foundationModel: "anthropic.claude-3-5-sonnet-20241022-v2:0",
    instruction: "Translate the user input text to Spanish. Only do that, noting more.",
    actionGroups: [
        {
            actionGroupName: "profile-management",
            description: "Functions to manage user profiles including loading and saving profile information.",
            actionGroupExecutor: {
                customControl: "RETURN_CONTROL"
            },
            functionSchema: {
                functions: [
                    {
                        name: "save_profile",
                        description: "Save or update the user's profile",
                        parameters: {
                            name: { type: "string" }, // <-- Required is not set
                        },
                    }
                ]
            }
        }],
    inputText: "Bonjour",
    // (Other arguments ommited for clarity...)
}));

When it does not work, I get this error

}

Observed Behavior

Not explicitely setting the optional attribute actionGroups.functionSchema.functions.parameters.my_parameter.requiredtriggers a cryptic Internal Server Error

Expected Behavior

Being able to not set required OR having it typed as not optional

Hey @maximelebastard ,

I can reproduce this issue -

Code I have

import { BedrockAgentRuntimeClient, InvokeInlineAgentCommand } from "@aws-sdk/client-bedrock-agent-runtime"
const bedrockClient = new BedrockAgentRuntimeClient({
    region: "us-east-1",
});
const res = await bedrockClient.send(new InvokeInlineAgentCommand({
	sessionId: "session_1",
    foundationModel: "anthropic.claude-3-5-sonnet-20241022-v2:0",
    instruction: "Translate the user input text to Spanish. Only do that, noting more.",
    actionGroups: [
        {
            actionGroupName: "profile-management",
            description: "Functions to manage user profiles including loading and saving profile information.",
            actionGroupExecutor: {
                customControl: "RETURN_CONTROL"
            },
            functionSchema: {
                functions: [
                    {
                        name: "save_profile",
                        description: "Save or update the user's profile",
                        parameters: {
                            name: { type: "string"}, // <--Use without "required"
                        },
                    }
                ]
            }
        }],
    inputText: "Bonjour",
    // (Other arguments ommited for clarity...)
}));
console.log(res)

the console log I have -

I will forward this issue to the team.

Thanks for the feedback!

Root cause - This is the interface of ParameterDetail , required is optional in AWS SDK but is required in the runtime.

In service doc - it's also marked as optional. I will contact service team to follow up this issue.
