How to Fix: Property 'files' does not exist on type 'EventTarget' error in typescript

The 'Property 'files' does not exist on type 'EventTarget' error in TypeScript occurs when trying to access the value of an input file in an Ionic 2 application. This issue affects developers who are using TypeScript with their JavaScript applications and are experiencing this specific problem.

This error can be frustrating because it prevents the application from functioning as expected, and the solution is not immediately apparent. However, by following the steps outlined below, you should be able to resolve this issue and get your application up and running smoothly.

🔍 Why This Happens

• The primary cause of this error is that the TypeScript compiler is unable to infer the type of the 'e' parameter in the event handler. This is because the 'e' parameter is optional, and the TypeScript compiler does not know what type it should be.
• Another possible cause is that the 'e.target.files[0]' expression is being evaluated before the event handler function has a chance to run. This can happen if the 'onchange' event is triggered by another event, such as a click or keypress.
