Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/590

I am attempting to use face-gcs-server along with Alpakka, specifically https://github.com/akka/alpakka/tree/master/google-cloud-storage/src and I am currently experiencing the issue where when you try to get the details of a bucket (i.e. GET http://0.0.0.0//storage/v1/b/<some-bucket>) the response is missing the location field in the JSON.

I understand that fake-gcs-server doesn't return a location field because fake-gcs-server doesn't really have a concept of location but since its a mandatory field this is causing alpakka gcs client to not work, the JSON deserialization is failing with

Message: Object is missing required member 'location'

Maybe it makes sense to add a -location parameter the options which can hardcode a location (such as "EUROPE-WEST3")? Alternately when you create a bucket that specifies a location this can be persisted so that its returned whenever you do GET http://0.0.0.0//storage/v1/b/<some-bucket>.

Yeah if that's a parameter on bucket creation we should persist it and return where applicable.

Do you know if any other fields are missing?

Unfortunately the JSON parser that is used short circuits as soon as it finds the first missing field so I only know that the location field is missing but for reference these are the fields that its looking for (all of which are mandatory)

/**
 * Represents a bucket in Google Cloud Storage.
 *
 * @param name The name of the bucket
 * @param location The location of the bucket, object data for objects in the bucket resides in physical storage within this region, Defaults to US.
 * @param kind The kind of item this is
 * @param id The ID of the bucket
 * @param selfLink The URI of this bucket
 * @param etag HTTP 1.1 Entity tag for the bucket
 */
final class Bucket private (
    val name: String,
    val location: String,
    val kind: String,
    val id: String,
    val selfLink: String,
    val etag: String
)

If this is not helpful enough I can print out the response to see if there are any other missing fields?

Oh ok from that type definition I assume the only thing missing is location. I can work on it some time this week, but let me know if you'd prefer to send a PR.

I think we probably want to:

take the region on createBucket
include it on getBucket
(maybe?) have a default region that's used for buckets sourced from the disk on startup

I am not that familiar with Go and its not that urgent for me so I am happy waiting if you are fine with working on it (otherwise let me know and I will try and work on it later on).

Yup sounds great from my end, having a command line arg such as default-region seems appropriate for the last point
