Minor issue: Internal Server Error in `registerInfra` when description is `null` #4228

Open smitthakkar96 opened 1 year ago

smitthakkar96 commented 1 year ago

Context:

We are trying to automate the installation of Chaos Infra in different namespaces using Kyverno. When playing around with the API to figure out how the registration flow works, I ran into this issue.

What happened:

When the description field in registerInfra call is empty as the docs say it's not required, the request fails with 500 Internal Server Error.

Logs:

runtime error: invalid memory address or nil pointer dereference

This works if you set the description as an empty string

What you expected to happen:

The request should be successful, or the documentation should say description is a mandatory field.

How to reproduce it (as minimally and precisely as possible):

mutation registerInfra($req: RegisterInfraRequest!) {
  registerInfra(
    projectID: "<PROJECT_ID>"
    request: $req
  ) {
    manifest
    token
    infraID
    name
  }
}
{
  "req":{
    "environmentID": "testing1",
    "name": "testing-cluster2",
    "infrastructureType": "Kubernetes",
    "infraScope": "namespace",
    "platformName": "Kubernetes",
    "infraNamespace": "sre-enablement",
    "infraNsExists": true,
    "infraSaExists": false,
    "serviceAccount": "sre-enablement-chaos",
    "skipSsl": false
  }
}

Setting description to empty solves the problem, so it's not a big deal, but putting this out there so if someone is trying to use API, they don't waste 2 hours trying to figure out why the API is not working as expected.

Will take a look at this issue, thanks for reporting @smitthakkar96
