Error when running `yarn develop`

Getting this at 3.0.0-beta.5:

Error: It appears like Gatsby is misconfigured. Gatsby related `graphql` calls are supposed to only be evaluated at compile time, and then compiled away. Unfortunately, something went wrong and the query was left in the compiled code.

Getting this at 2.0.0:

Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://fb.me/react-invalid-hook-call for tips about how to debug and fix this problem.

Hi,

v3.1.0 is the only one you should use.

Do you have a Gatsby open-source site on which you try to add this plugin?
Or could you share more details about your existing setup?

[garrettg123]

Sure, it's a monorepo. I just created a fresh Gatsby site in a new package inside the monorepo. Using Node v12.16.2. Here is my package.json:

  "name": "web-gatsby",

This is where I get the error:

TypeError: Cannot read property 'plugins' of undefined

When I add a log:

const customizeExpoJsLoader = config => {
  const expoJsLoaderRule = getExpoJsLoaderRule(config);
  console.log(expoJsLoaderRule.use) // MY CODE
  expoJsLoaderRule.use.options.plugins = expoJsLoaderRule.use.options.plugins || []; // We need to add the gatsby static queries babel plugin to expo js loader

I get:

[
  {
    options: { stage: 'develop-html', configFile: true, compact: false },
    loader: '/Users/gsquare567/Sites/think/web-gatsby/node_modules/gatsby/dist/utils/babel-loader.js'
  }
]

but the plugin is expecting it to be an object, so expoJsLoaderRule.use.options is undefined and expoJsLoaderRule.use.options.plugins throws the error.

[garrettg123]

When I try changing it to

expoJsLoaderRule.use[0].options.plugins = expoJsLoaderRule.use[0].options.plugins || []; // We need to add the gatsby static queries babel plugin to expo js loader

It seems to fail from a different error. It looks like the console log prints twice, so the loader function runs twice. Here's the output:

success run queries - 0.069s - 5/5 72.83/s

Hi,

Will have to look at all this.
Probably won't have much time this week though.

I haven't tested this plugin in a monorepo yet.
I guess you also use yarn workspace and hoisting dependencies.
This is definitively something I want to support, to make sharing code between static web and mobile easy. I also want to migrate my own site to a monorepo when it's done.

There's another issue about monorepos here but it seems unrelated: #32

Same thing here, were you able to solve it ?

[garrettg123]

No, I gave up on it. I'd try `nohoist: ["**"]` and see if that works. That should make your package within a monorepo act just like a standalone package. If it still doesn't work, I'm guessing there's something wrong with it even outside of a monorepo.

Oh yeah it worked, thanks ! I don't why I was trying to add nohoist: ["**/gatsby-plugin-react-native-web/**"]

[slorber]

Sorry that it does not work out of the box, I'll try to improve the monorepo support when I have time

[cmaycumber]

I was able to fix this in my monorepo by switching the logic for finding the expo loader to:

const getExpoJsLoaderRule = (config) => {
  const { getExpoBabelLoader } = require('@expo/webpack-config/utils');
  const expoJsLoader = getExpoBabelLoader(config);
  console.log(expoJsLoader);
  return expoJsLoader;
};

However, I started running into issue #38. I'm not sure whether or not it's the new logic I added in or something related to the versions I'm using for expo and gatsby.
