[bug]: Can't add url config for lambda in local stack using aws-sdk

[spelexander]

Hi! first off thanks for a useful library for emulating AWS resources locally.

The issue I'm encountering is using the nodejs aws-sdk to create resources in localstack.

If I create a lambda, and then try to create/list/get a URL config for the lambda I get the following error which provides nothing to go off of for investigation:

See an reproducible example below, assuming 'test-lambda' has already been created:

import { Lambda } from 'aws-sdk';

import { buildWorker, packageWorker } from './workers';

const lambda = new Lambda({
  region: 'us-east-1',
  endpoint: 'http://localhost:4566',
});

const name = 'test-lambda';

it('Test create resources', async () => {
  lambda.addPermission({
    FunctionName: name,
    Action: 'lambda:InvokeFunctionUrl',
    Principal: '*',
    FunctionUrlAuthType: 'NONE',
    StatementId: '/',
  });

  try {
    // THIS FAILS
    // So does the list, or get commands
    const result = await lambda
      .createFunctionUrlConfig({
        FunctionName: name,
        AuthType: 'NONE',
      })
      .promise();
    console.log('result: ', result);
  } catch (e) {
    console.error(e);
  }
});
