opa-data-filter-mongo-demo's Issues

NPE while converting OPA response

I am trying out opa-data-filter-demo. OPA server is setup locally
I am getting below error when I try to access http://localhost:8081/pets

Assuming the OPA response is not correct I directly hit OPA POST http://localhost:8181/v1/compile. OPA gave below response

OPA Response

{ "result": { "queries": [ [ { "index": 0, "terms": [ { "type": "ref", "value": [ { "type": "var", "value": "eq" } ] }, { "type": "string", "value": "alice" }, { "type": "ref", "value": [ { "type": "var", "value": "data" }, { "type": "string", "value": "pets" }, { "type": "var", "value": "$02" }, { "type": "string", "value": "owner" } ] } ] }, { "index": 1, "terms": { "type": "ref", "value": [ { "type": "var", "value": "data" }, { "type": "string", "value": "pets" }, { "type": "var", "value": "$02" } ] } } ] ] } }

Error message
`{
"query" : "data.petclinic.authz.allow = true",
"input" : {
"path" : [ "pets" ],

}
