Error: Cannot read property 'text' of undefined

[bitsnaps]

Hi,
I get an error when testing FlushPromises :

Cannot read property 'text' of undefined

The app is working fine, it runs correctly, I've even added a line to display <MessageDisplay /> in the AppHeader.vue to make sure the json-server is up and running.
The beginning of the log:

    console.error node_modules/vue/dist/vue.runtime.common.dev.js:621
      [Vue warn]: Error in render: "TypeError: Cannot read property 'text' of undefined"

      found in

      ---> <Anonymous>
             <Root>
    console.error node_modules/vue/dist/vue.runtime.common.dev.js:1884
      TypeError: Cannot read property 'text' of undefined

Hi. I've added this code after jest.mock() call:
beforeEach(() => { jest.clearAllMocks(); //todo don't forget to clear all mocks before each test! })
and it seemed to clear that error.
