After I deployed changes to Azure dev environment, the backoffice is not working. It opens empty page. The frontend is working and recent code changes are working too. Backoffice is working in localhost and dev backoffice was working till yesterday. I cleared browser caching and cleared site data. No change happened. I also tried in different browsers and in private mode. The backoffice is still blank. In the debug console, below errors were logged with many other 500 errors. Uncaught ReferenceError: angular is not defined at changedialog.controller.js:54:1 at changedialog.controller.js:1:1 Uncaught ReferenceError: jQuery is not defined at Application?umb__rnd=acdd6c19b5c163ff26ca1f3b2ef3f1db1a881876:2:1 at i (LazyLoad.min.js:1:214) at HTMLScriptElement.p (LazyLoad.min.js:1:541) Have anyone faced similar issue? Please suggest a solution.
