Hi, I am getting 404 Error: Not Found when I access "http://localhost:3000/socialLogin"

Hey those are api calls to be used with POST requests, you cannot access them via browser url (get) request. You have to start the project with ionic emulate ios for example if using iOS or ionic run android for Android.

Hi, I keep getting "Service unavailable, make sure you are online" when I run "ionic run android" command. It is failing @ socialLogin function. When I tried with Postman to access to the URL "http://localhost:3000/socialLogin" I get successful response. I can send screenshot if needed

Check the common issues heading in the description section of this page. If you're using Android Emulator or testing on a Smartphone, you cannot access your computer's localhost. In the Frontend/www/js/services.js you have to replace all the localhost references with your computer external ip such as 192.x.x.x. Find out what your computer's IP is and put it instead of localhost. Make sure the smartphone and your computer are on the same wifi network or your server is accessible globally.
