When I am running my AWS Typescript lambda with ESM I get the following warning: You cannot annotate the main segment in a Lambda execution environment. Am not sure only what the cause could be since I wasnt able to find a lot of information online about it.

My handler looks something like this:

class Lambda implements LambdaInterface {

    private readonly targetService= new TargetService();

    @logger.injectLambdaContext({ logEvent: true })
    @catchError({ tracer: tracer })
    public async handler(event: APIGatewayProxyEvent, context: Context): Promise<APIGatewayProxyStructuredResultV2> {
        ...
    }
}

const handlerClass = new Lambda();
export const handler = handlerClass.handler.bind(handlerClass);

Could someone maybe explain what this warning means and where I should look to solve said issue?
