getting in valid hook error in a re write of a clients app... (upgrading code)

mobx 6.3.8 mobx react 7.2.1 and mobx-state-tree 5.0.5 React 17.0.1 RN 0.64.3

i feel like the error is here. i googled the code line for use stores and it led me to the deprecated site... i dont know where to find new handling in the https://mobx.js.org/react-integration.html site... what would this be called?

I have an application built with NextJs (and React) and mobx-state-tree (but could be context or redux) as a package manager. All the stores are created and handled in an npm package called SMK (state management kit) that I created to make the sub-stores reusable in my mobile and web application.

How it works:

1. Create the sub-store with models, actions and views on the SMK and export it as a module.
2. Add the SMK using yarn add @my-repo/smk.
3. Create the root store in my app and import the sub-store from SMK as a child of the root store.
4. Build and start the app and everything is working well.

But I need to run and publish the SMK locally to make it easier development. The solution I used to use is yalc.

Using yalc and running it locally this is the process:

1. In the SMK, runs yarn start. (This will do nodemon --ignore src/index.ts -e js,ts,tsx,json --watch src/ --exec yalc push --scripts)
2. In the APP, runs yalc add @my-repo/smk. (This will add a dependency like "@my-repo/smk": "file:.yalc/@my-repo/smk").
3. In the APP, runs yarn build and then yarn start

And voila! Everything is working perfect, any change I did locally on my SMK is working perfectly on the APP.

BUT, when I run yarn dev that do next dev as default of NextJs it doesn't work.

This is the error I'm facing:

Error explanation: As I only added the setTestingState and testingState locally, it's saying that it doesn't exist.

Possible reason: The fast refresh is not refreshing the cache properly.

I've tried:

• Add // @refresh reset to force it, but didn't work.
• Stop and start the application.
• Build, start and then run dev. (works for build and not for dev)

What is the solution/workaround to solve this issue with yarn dev and yalc?

I'm learning mobX-state-tree, and in their tutorial code, i see this

I am trying to set the vehicles array to the array that I am getting from the store. However, it seems that Typescript is complaining about something.

My model looks like this:

When I am creating a new session (or try to access from an other computer) in Vaadin Flow I get this error:

Can't move a node from one state tree to another

From this link, I read something about UI and getUIId().

However, I don't understand how I should change my application in order to fix the error.

it's the first time I use react-intl with Mobx state tree.

Basically I have two buttons in the header (it and en) that on click set the current language saved in a Mobx State Tree variable.

Something like this.

In my state:
