[v2] Page hot reload error

[porfirioribeiro]

Description

After this merge #6226
The way as pages are stored in redux changed, so this line

gatsby/packages/gatsby/src/bootstrap/page-hot-reloader.js

Line 58 in d1423b1

.pages.filter(p => !_.includes(statefulPlugins, p.pluginCreatorId))

Gives error

Steps to reproduce

Edit any file so it needs to hot reload

Expected result

Reload the page content

Actual result

error UNHANDLED REJECTION


  TypeError: store.getState(...).pages.filter is not a function

  - page-hot-reloader.js:65
    [website]/[gatsby]/dist/bootstrap/page-hot-reloader.js:65:28

I think here it might also give errors

gatsby/packages/gatsby/src/utils/websocket-manager.js

Line 40 in d1423b1

const page = pages.find(p => p.path === pagePath)

gatsby/packages/gatsby-plugin-page-creator/src/gatsby-node.js

Line 70 in d1423b1

.pages.filter(p => p.component === path)
