Android Error : java.lang.NullPointerException - org.json.JSONArray.length()

[kevinfavv]

Error:
java.lang.NullPointerException: Attempt to invoke virtual method 'int org.json.JSONArray.length()' on a null object reference

My capacitor.config.json in my app root directory looks good...

I already sync capacitor,
Capacitor 3.0.1 (every dependencies are updated)

[kevinfavv]

My bad !
I had two configuration files : One in TS (not supported yet), and one in JSON.
when i do the synchronization the JSON file get deleted (because it is detected as unused) what causes the error.

Hope this will help someone !
