Expected Behavior

Here is my project config:

const project = new ProjectConfig({
    defaultStage: 'dev',
    plugins: [
        new AlexaCli({
            askProfile: 'mm',
            locales: {
                en: ['en-US'],
            },
            files: {
                'skill-package/skill.json': {
                    manifest: {
                        events: {
                            subscriptions: [
                                {
                                    eventName: 'SKILL_ACCOUNT_LINKED',
                                },
                            ],
                        },
                    },
                },
            },
        })
    ],
    stages: {
        dev: {
            endpoint: DEV_LAMBDA_ARN,
            plugins: [
                new AlexaCli({
                    skillId: DEV_SKILL_ID,
                    files: {
                        'skill-package/skill.json': {
                            manifest: {
                                events: {
                                    endpoint: {
                                        uri: DEV_LAMBDA_ARN,
                                    },
                                },
                            },
                        },
                    },
                }),
            ],
        },
        prod: {
            endpoint: PROD_LAMBDA_ARN,
            plugins: [
                new AlexaCli({
                    skillId: PROD_SKILL_ID,
                    files: {
                        'skill-package/skill.json': {
                            manifest: {
                                events: {
                                    endpoint: {
                                        uri: PROD_LAMBDA_ARN,
                                    },
                                },
                            },
                        },
                    },
                }),
            ],
        },
    },
});

Running jovo build:platform alexa should produce a valid skill package.

Current Behavior

Currently jovo build:platform alexa fails with the error below.
I see that the build hook for Alexa runs 4 tasks. After adding debug logs, I found out that the error is thrown inside

jovo-framework/platforms/platform-alexa/src/cli/hooks/BuildHook.ts

Line 374 in b7f56c5

buildProjectFiles(): void {

More precisely the error comes from the call to

jovo-framework/platforms/platform-alexa/src/cli/hooks/BuildHook.ts

Line 446 in b7f56c5

checkLocales(projectFiles: FileObject): void {

The error is thrown by the first of these 2 for loops because privacyAndCompliances is undefined.

I think that privacyAndCompliances and publishingInfos should be set by default to an empty object if they are undefined, here.

Does it make sense?
