uaa list-clients: json: cannot unmarshal string into Go struct field Client.resource_ids of type []string

[Houlistonm]

Version

$ uaa version
0.7.0 8b3ea1f

Command

uaa list-clients

Returns

An unknown error occurred while parsing response from https://uaa.run.markspcffoundry.com/oauth/clients?count=100&sortOrder=ascending&startIndex=1. Response was <18150 characters of redacted json>: json: cannot unmarshal string into Go struct field Client.resource_ids of type []string

The <18150 bytes of redacted json> is from me, not the uaa client.

If I take the 18150 characters of json and pipe through jq it processes successfully. If I run the command a second time with the --verbose flag, and compare the json from that output to the json in the error message, it is a perfect match.

We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.

• According to UAA API specs, GET /oauth/clients/{client_id} should return resource_ids attribute as an Array.
• Actual UAA implementations return resource_ids either as an array of strings or as a simple string.

Example of querying UAA v4.19.2:

$ uaa curl /oauth/clients|jq '.resources[]|select(.resource_ids|type == "string")'
{
  "scope": [
    "cloud_controller.admin",
    "cloud_controller.read",
    "cloud_controller.write",
    "openid",
    "zones.*.*",
    "zones.*.*.*",
    "zones.read",
    "zones.write",
    "scim.read"
  ],
  "client_id": "identity",
  "resource_ids": "none",
  "authorized_grant_types": [
    "authorization_code",
    "client_credentials",
    "refresh_token"
  ],
  "redirect_uri": [
    "REDACTED",
    "REDACTED*"
  ],
  "autoapprove": true,
  "authorities": [
    "zones.read",
    "zones.write",
    "scim.zones",
    "uaa.resource",
    "uaa.admin",
    "cloud_controller.admin"
  ],
  "lastModified": 1551175600000
}

So, even with uaa-cli is API compliant, it is not compatible with the actual UAA servers.

Just to follow up

$ uaa version 0.10.0 8626b94

OM/PAS = 2.8.5

Problem persists.

Hello. The /oauth/clients api does have some quirks and I agree that this cli should handle those.

We don't have plans to start work on this CLI again at the moment, but if we do this issue will be addressed then.
