TypeError: C:\Users\MY HP\Desktop\projectt updating\my_project\client\polyfills.js: this.setDynamic is not a function

[Er-Ramanand-Dubey]

can anyone help me please,
my polyfillsa.js file looks like this.

`import includes from 'core-js/library/fn/string/virtual/includes'

import repeat from 'core-js/library/fn/string/virtual/repeat'

import assign from 'core-js/library/fn/object/assign'

import from from 'core-js/library/fn/array/from'

console.log('Load your polyfills')

String.prototype.includes = includes

String.prototype.repeat = repeat

Object.assign = assign

Array.from = from

// import 'core-js/features/array/includes'
// import 'core-js/features/string/repeat'
// import 'core-js/features/array/from'
// import assign from 'object-assign'
// Object.assign = assign

`

Could you provide a GitHub repository link with the code that is causing you problems?

If you update to the latest version of Next (or any version past 9.3) these polyfills are all included for you, so you could remove this polyfills file.
