CloudEvent registration method should be camelCase

[matthewrobertson]

"Cloud Event" is two words so the "E" should be capitalized:

import * as functions from '@google-cloud/functions-framework';

functions.cloudEvent('helloCloudEvent', (cloudEvent) => {
  console.log('Hello, CloudEvent!');
});

[grant]

Nice catch. cloudEvent should be the correct lower camel case. 👍🏻

Note: CloudEvent is one word, but the outcome of using cloudEvent is the same.
