aws-sdk V3 for NodeJS throws 404: UnknownError when calling ListFunctionsCommand

[eranbo]

Using aws-sdk V3 for nodeJs is not working with Lambda.
When running the next code:

const client_ = new LambdaClient({ endpoint: 'http://localhost:5000'});

const res = await client_.send(new ListFunctionsCommand());

The following exception is raised:
