Error: JavaProxy is not defined

March 22, 2016 — by Dan Wilson

Some NativeScript users are asking about an error occurring when running an application. The error text resembles the below:

java.lang.RuntimeException: Unable to create application com.tns.NativeScriptApplication: com.tns.NativeScriptException: 

Error calling module
function;ReferenceError: JavaProxy is not defined File: ", line: 1, column: 265;


This is caused by an incomplete upgrade of the NativeScript framework. If you have this issue, please follow the 3 steps outlined in our NativeScript Upgrade Instructions document.

Note: After every upgrade, you should ensure you go through this process. Bookmark it and save yourself some time.

Happy NativeScripting!
