Getting error message "Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'url')" on the console and breaking the APIs currently running. 

adrum-latest version: v:23.3.1.4273

I tried removing the app agent (adrum-latest.js) from index.html and application is working fine. please suggest any approach to handle these type of errors as this is causing crashing of the application.

Hello @Gopal.Abbineni,

Just relaying some information I found here. 

Can you confirm if SPA2 is enabled in adrum configuration?

Please see this doc for the relevant configuration:
https://docs.appdynamics.com/appd/22.x/latest/en/end-user-monitoring/browser-monitoring/browser-real...

(you may need to adjust the documentation for your Controller version #)
config.spa = {
"spa2": true
};
