GeezerVison is showing github.com — cors error · Issue #524 · fullstackreact/google-maps-react
Description
My project was working fine last week and now I'm getting cors errors. I have been in contact with google technical support to ensure that my key is set up properly and I can make fetch calls to the library without cors issues as well. The errors I'm seeing output in my console is:
Uncaught (in promise) lf {message: 'loaderCB01632903299228 is not a function', name: 'InvalidValueError', stack: 'Error\n at new lf (https://maps.googleapis.com/m…ons&v=3&language=en&onerror=ERROR_FUNCTION:309:44'}

I rebuilt the project again and now its working? I don't understand what went wrong here. I downloaded my repository, ran npm install to download the node modules and then npm start as usual when it wasn't working. Where did I go wrong?
