Describe the bug

Trying to generate a state and then use the result to get a zipCode.

const state = faker.location.state({ abbreviated: true });
const zipCode = faker.location.zipCode({ state: state });

Getting the following error:

Uncaught u: The locale data for 'location.postcode_by_state' are missing in this locale.
  Please contribute the missing data to the project or use a locale/Faker instance that has these data.

I've verified that the response from state is a correct 2 character state code (i.e. PA, GA, CT).

Also tried passing a string to no avail.

const zipCode = faker.location.zipCode({ state: "GA" });

The error is getting thrown from line 83 here:

faker/src/modules/location/index.ts

Line 83 in 192b540

this.faker.definitions.location.postcode_by_state[state];

I assume you want to generate the postcodes for en_US?
If yes, please use fakerEN_US.location.zipCode({state:'GA'})

or add the missing data from the en_US locale:

faker.rawDefinitions.location.postcode_by_state = en_US.location.postcode_by_state;

Does this solve your issue?
