The issue you're encountering is not primarily related to Chrome DevTools — those .json
file errors can be safely ignored.
However, the missing toastr.js.map
file might be contributing to the problem. While it’s not critical, it's recommended to update the Toastr library manually to ensure compatibility with Mendix 10.
After updating:
Clean the deployment directory (Project > Clean Deployment Directory
).
Run the app again.
Press F12 in your browser to open Developer Tools, then check the Console tab for more detailed error messages. This will help identify the root cause of the blank screen.
These steps should give you more insight into what’s failing and guide you toward a solution.
I hope this will help.
