Failed to load resource: net::ERR_FILE_NOT_FOUND

[IntelligetProjects]

hi all
I am using ionic angular to build Andriod/IOS app.

ionic version: 6.17.0
angular version: 11.2.14
gradle version: 6.9.1
cordova version:10.0.0

but I am facing this wall all the time I am trying to build it, the build is successful but when I try to build the Gradle

and run it in the android emulator this issue raises in the console:

braintreeClient.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
braintreePaypal.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND

/assets/icon/favicon.png:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
css2:1 Failed to load resource: the server responded with a status of 404 (Not Found)

when hovering on the error below URL that appears:

file:///assets/others/braintreeClient.js

this file is there in the assets folder and its extinction is .js

if I could find any advice I will be thankful.
