I am getting this error while writing the cypress tests. I am using cypress code coverage. This is my test code.

describe("hello world text testing", () => {
before(() => {
cy.visit("/");
cy.waitForReact(1000, "#root", "node_modules/resq/dist/index.js");
});

it("login test", () => {
cy.react("Login");
});
});

I have the same issue after updating to Cypress 10.7.0 and cypress-react-selector 3.0.0

Same Issue with React 18.
Is there any bug fix?
Is someone still maintaining this repository?
Seems like it was already reported months ago.

waitForReact now works for me; this needed the following changes; however, react(...) then fails for me.

package.json -- make sure to force the just released new version of resq that works with React 18.

{
  "resolutions": {
    "resq": "^1.11.0"
  },
}

In component-index.html add an id= attribute the data-cy-root div element:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>Components App</title>
  </head>
  <body>
    <div id="__cy_root" data-cy-root></div>
  </body>
</html>

In cypress.config.ts tell cypress-react-selector the id of this root element:

import { defineConfig } from "cypress"

export default defineConfig({
  component: {
    devServer: {
      framework: "create-react-app",
      bundler: "webpack",
    },
  },
  env: {
    'cypress-react-selector': {
      root: '#__cy_root',
    },
  },
})

this repo is not dead btw. We dont have an active usecase with react 18 at this moment. We will evaluate it soon. Looking for active contributors/maintainers
