TypeError: Cannot read property 'type' of undefined

I have a valid Query that passes with tester.test however when I tester.mock with a fixture, then I'm seeing:

TypeError: Cannot read property 'type' of undefined
      at validateFixture (node_modules/easygraphql-tester/utils/fixture.js:50:27)
      at validateFixture (node_modules/easygraphql-tester/utils/fixture.js:100:19)

I debugged and it appears the issue is related to a simple name of type String which the mocker has no selectedType, hence the error at this line: https://github.com/EasyGraphQL/easygraphql-tester/blob/master/utils/fixture.js#L46

  if (schema[selectedType.type]) {

If I simply add a null check, all my tests pass:

  if (selectedType && schema[selectedType.type]) {

I'm happy to open a PR here, but I'd first want a core dev here to weigh in on what might be the issue and if this would be a valid check to simply add a null check on selectedType

@estrada9166 Sure thing, here it is: https://github.com/engineersamuel/easygraphqlrepro with instructions.

Thanks for sharing it! what I can notice is that you are missing on the GraphQL schema, the field storageAccountName that is being tried to be mock

If you update it for - it may work

type StorageDirectory {
  name: String!
  storageAccountName: String!
  files(sampleSize: Int): [StorageFile]
}

Definitely something that can be improves is the error message in this case in case you want to open a PR!

Ahhh, great catch! Not sure on my bandwidth for a PR here, but let's leave this open and I'll try to get to it.
