ERROR in main.preload
Module not found: Error: Can't resolve 'mailmagnet/app/src/app/api/main.preload.ts' in '/Users/arkadevbanerjee/Desktop/Development/ui-remote'
Did you mean './mailmagnet/app/src/app/api/main.preload.ts'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.

[arkad-cm]

'main.preload': 'mailmagnet/app/src/app/api/main.preload.ts'

was relative before and was breaking. After changing join to resolve it is now absolute

/Users/arkadevbanerjee/Desktop/Development/ui-remote/mailmagnet/app/src/app/api/main.preload.ts

And after this the error gets fixed!
