React Scan ran into a problem

[tydolla00]

Hello, I did a fresh install of react-scan into my Next project and got this error.

Versions

"next": "^15.1.2", "react": "^19.0.0", "react-scan": "^0.2.14",

React Scan ran into a problem undefined is not an object (evaluating 'r.__H')

I've got the imports at the top in both the layout and React Scan component. I tried deleting node modules, removing the react-scan package and reinstalling. It occurs in both chrome and safari.

I even have _debug: "verbose", in the react scan component and am not getting any logs in the console. I am able to see the rerenders but I would like to see the fps counter as im debugging animations. Any assistance would help, thanks!

Preact error. Most likely happens when you bundle.

I feel like it should be installed as a devDependency, have you tried it? Also the script should work fine instead of installing in the project
