How to fix Undefined: Property error setTargetNode

I am currently compiling my react project, and it compiles successfully however upon loading the page i get this error:

Uncaught (in promise) TypeError: Cannot read property 'setTargetNode' of undefined
at p (Target.js:40)
at Ba (react-dom.production.min.js:5029)
at Ha (react-dom.production.min.js:5123)

at Pu (react-dom.production.min.js:5925)
at Su (react-dom.production.min.js:5860)

The target.js I believe is a file from the react-popper node module. Which was working prior to updating the package file. The page loads all elements on the page load then the page goes totally blank.

I have tried deleting my package-locked.json and formed a new one however the issue still persists. The project however works fine in the dev environment.

what does package.json has to do with the described error? Read the error again, it describes exactly what is wrong: inside the file Target.js you are trying to access a property called setTargetNode of some object, and that object happened to be undefined when the code reached that point. it even points you to the exact line: (Target.js:40).

Go there, follow the flow of data to that object- where it is created / initialized? are you sure it is initialized before the access to setTargetNode is happening? try it yourself first, if still no success please post the code related to the error so we can better help.
