No output when creating muting rules

[bertrandretif]

Description

When I create a muting rule with newrelic-cli, the rule is properly created but output JSON is empty.
Muting rule Id should be returned as it is with curl command.

Go Version

Go not installed, use of newrelic-cli

$ newrelic --version
newrelic version 0.78.17

Current behavior

When I run this command (generated from NerdGraph API Explorer), returned JSON is empty

NEW_RELIC_REGION=eu NEW_RELIC_API_KEY=XXXXX newrelic nerdgraph query 'mutation {
  alertsMutingRuleCreate(
    accountId: 00000
    rule: {name: "dev-paris deployment 2", description: "Muting rule created with newrelic-cli", enabled: true, condition: {conditions: {attribute: "conditionId", operator: IN, values: ["XXXX", "YYYY"]}, operator: AND}}
  ) {
    id
  }
}' 
{}

Expected behavior

Get the same output than curl command:

NEW_RELIC_REGION=eu NEW_RELIC_API_KEY=XXXXX newrelic nerdgraph query 'mutation {
  alertsMutingRuleCreate(
    accountId: 000000
    rule: {name: "dev-paris deployment 2", description: "Muting rule created with newrelic-cli", enabled: true, condition: {conditions: {attribute: "conditionId", operator: IN, values: ["XXXX", "YYYY"]}, operator: AND}}
  ) {
    id
  }
}' 
{"data":{"alertsMutingRuleCreate":{"id":"XXXXX"}}}

Steps To Reproduce
