Hi, when talking directly to the Cerbos gRPC service, how do I represent the attributes for a principal and for a resource in JSON? I need this for testing the gRPC in Postman and K6. Trying to do similar to this example in the playground https://play.cerbos.dev/p/LXjgi62fb63c1QypYuZhsyRK3cTMcRx5 This is what I have but it does not work.

{

"requestId": "123123",

"version": "default",

"principal": {

"id": "<mailto:email@email.com|email@email.com>",

"roles": [

"user"

],

"attr": [

{

"key":"salesreps",

"value": {

"kind": {

"listValue": ["1","2"]

}

}

}

]

},

"resources": [

{

"resource": {

"kind": "customer",

"version": "default",

"id": "12345",

"scope": "teamb",

"attr": [

{

"key":"salesrep",

"value": {

"kind": {

"stringValue": "2"

}

}

}

]

},

"actions": ["VIEW"]

}

]

}

The attrbuite field should just be a map eg

"principal": {
    "id": "alice",
    "roles": ["employee"],
    "attr": {
      "department": "accounting",
      "geography": "GB",
      "team": "design"
    }
  },

ok let me try grpcurl, it could be a postman issue but it doesn't like it when I did this. It expects the attr to be an array.

Odd - let me us know how you get on

will do

The protobuf type is

map<string, google.protobuf.Value>

grpc curl works, must be how postman did reflection on the grpc end point.
