TypeError: app.get is not a function

First off, thanks for the plugin! I'm in the process of implementing search for a site that uses Sanity as a headless CMS and Gridsome for SSG.

I'm getting the following error when running gridsome develop:

Serving search index
TypeError: app.get is not a function
    at CreateSearchIndex.api.configureServer.app (/Users/zack/Sites/sanity/sanity-gridsome-blog/web/node_modules/gridsome-plugin-flexsearch/gridsome.server.js:39:9)

Here are the contents of package.json with the versions of Gridsome and the Flexsearch plugin:

{
  "name": "sanity-gridsome-web",
  "private": true,
  "scripts": {
    "build": "gridsome build",
    "dev": "gridsome develop",
    "explore": "gridsome explore"
  },
  "dependencies": {
    "@gridsome/plugin-google-analytics": "^0.1.0",
    "@sanity/image-url": "^0.140.15",
    "dotenv": "^8.1.0",
    "gridsome": "^0.7.1",
    "gridsome-plugin-flexsearch": "^0.1.9",
    "gridsome-source-sanity": "^1.0.1",
    "sanity-blocks-vue-component": "^0.1.0"
  },
  "devDependencies": {
    "node-sass": "^4.12.0",
    "sass-loader": "^8.0.0"
  }
}

And finally, here's the config of my collection as well as the Flexsearch plugin in gridsome.config.js:

module.exports = {

...

  plugins: [
    // Sanity source plugin config
    {
      use: 'gridsome-source-sanity',
      options: {
        ...clientConfig.sanity,
        typeName: 'Sanity',
        token: process.env.SANITY_TOKEN,
        overlayDrafts: !isProd,
        watchMode: !isProd
      }
    },
    // Flexsearch plugin config
    {
      use: 'gridsome-plugin-flexsearch',
      options: {
        collections: [
          {
            typeName: 'Sanity',
            indexName: 'Sanity',
            fields: ['title']
          }
        ],
        searchFields: ['title']
      }
    }

...

  ]
}

Any info on what may be causing this would be greatly appreciated. Thanks again!

Hey @zacklerner!

I believe that the api.configureServer hook was added in gridsome v0.7.3. So I am afraid that to use this plugin, you will need to update to at least that version...

Let me know if that doesn't fix the issue...

@thetre97 That resolved the error! Thanks so much for the quick response.

No problem, thanks for raising it - I have added a note about that on the readme...
