vuex-persist: Cannot run unit tests

I am attempting to use vue-test-utils and jest to run some unit tests on my vuex actions. I am running into the error below. Any ideas on how I can get this resolved?

 FAIL  test/unit/specs/masternode/Provision.spec.js
  ● Test suite failed to run

    TypeError: Cannot read property '_config' of undefined

    
      
      at new VuexPersistence (node_modules/vuex-persist/dist/index.js:133:44)
      at Object.<anonymous> (src/store/index.js:60:17)

      at Object.<anonymous> (src/store/modules/index.js:7:12)
      at Object.<anonymous> (test/unit/specs/masternode/Provision.spec.js:27:16)

Here is my spec so far:

describe('AppActions', () => {
  const vuexLocal = new VuexPersist({
    storage: window.localStorage,
    modules: ['app', 'masternode', 'marketplace'],
  })
  let store

  beforeEach(() => {
    store = new VuexStore ({
      plugins: [vuexLocal.plugin]
    })
  })
})

Sorry I had been really swamped by work. I’ll fix this, this week.

Same issue here, we are using vuex-persist to store some credentials on the sessionStorage for a company internal tool but it seems that it is currently not possible to run tests. Same error as above.

Thanks @championswimmer , I’ve tried v1.1.6 … original error disappeared, but a new one came up :

 FAIL  test/unit/specs/ProjectSwitch.spec.js
  ● Test suite failed to run

    TypeError: Cannot read property 'getItem' of undefined
