Paypal api – Error: Uncaught (in promise): BraintreeError: options.authorization is required when instantiating a client

I am actually trying to implement braintree using Angular with asp.net core. But i am facing an issue, I don’t understand how to solve it. I am follwing this article. I am using version 14 of angular. I have doing exactly the same as mentioned article. I don’t know which authorization it is demanding. when i run the application, in the braintree UI, I failed to input Card Number ,Expiration date,CVV maybe for this error. here is my code:-

app.component.ts

import { HttpClient } from '@angular/common/http';
import { Component, OnInit } from '@angular/core';
import * as braintree from 'braintree-web';

@Component({
  selector: 'app-paypal',
  templateUrl: './paypal.component.html',
  styleUrls: ['./paypal.component.css']
})
export class PaypalComponent implements OnInit {

  CToken: any;
  hostedFieldsInstance: braintree.HostedFields;
  cardholdersName: string;
  

  constructor(private http: HttpClient) { }

  ngOnInit(): void {
    this.getToken();
    this.createBraintreeUI();
    
  }

    getToken() {
    this.http.get('https://localhost:5001/api/paypal').subscribe({
      next: response => this.CToken = response,
      error: error => console.log(error)
    })
    console.log(this.CToken);
  }



  createBraintreeUI() {
    braintree.client.create({
      authorization: this.CToken
    }).then((clientInstance) => {
      braintree.hostedFields.create({
        client: clientInstance,
        styles: {
          // Override styles for the hosted fields
        },
        

       
        fields: {
          number: {
            selector: '#card-number',
            placeholder: '1111 1111 1111 1111'
          },
          cvv: {
            selector: '#cvv',
            placeholder: '111'
          },
          expirationDate: {
            selector: '#expiration-date',
            placeholder: 'MM/YY'
          }
        }
      }).then((hostedFieldsInstance) => {

        this.hostedFieldsInstance = hostedFieldsInstance;

        hostedFieldsInstance.on('focus', (event) => {
          const field = event.fields[event.emittedBy];
        });

        hostedFieldsInstance.on('blur', (event) => {
          const field = event.fields[event.emittedBy];
        });

        hostedFieldsInstance.on('empty', (event) => {
          const field = event.fields[event.emittedBy];
        });

        hostedFieldsInstance.on('validityChange', (event) => {
          const field = event.fields[event.emittedBy];
          if (field.isPotentiallyValid) { 
            
          } else {
           
          }
          
        });
      });
    });
  }


   // Tokenize the collected details so that they can be sent to your server
   tokenizeUserDetails() {
    this.hostedFieldsInstance.tokenize({cardholderName: this.cardholdersName}).then((payload) => {
      console.log(payload);
     console.log("Bro! this is payload!!!"+payload.nonce);
      // submit payload.nonce to the server from here
    }).catch((error) => {
      console.log(error);
      // perform custom validation here or log errors
    });
  }

    Check order of asynchronous requests.

    It appears you’re not including your Braintree token in your request.

    This is likely happening because you’re making one asynchronous request before another completes.

    A simple way to fix this would be to move the call to this.createBraintreeUI() inside the response to you token request. That way you would only make the second request after the first completes.

    Something like this:

      ngOnInit(): void {
    this.getToken();    
  }

  getToken() {
    this.http.get('https://localhost:5001/api/paypal').subscribe({
      next: response => { 
        console.log(this.CToken);
        this.CToken = response;
        this.createBraintreeUI(); 
      },
      error: error => console.log(error)
    })

  }

    There may be more issues, as this is a complex integration with Braintree, but if you check that console.log() statement you have and it’s showing your token, and the token looks correct, then you’re on the right path.

    (For instance, you might have another problem where you can’t pass authorization: this.CToken there in the first line of your this.createBraintreeUI() function. You might have to set authorization to a property of this.CToken. So look at the console.log statement showing your token and see if it looks correct. )

    import Permissions from 'react-redux-permissions';

    First I use

    <Permissions allowed={[]}>

    Fix

    <Permissions allowed={['']}>

    https://i.stack.imgur.com/to6tV.png

    Second Way

    check condition inside and write on

    <Permissions></Permissions>

    Example:

        Wrong

  const permission = ['show'] || []

  `{name === 'About' &&
     <Permissions allowed={permission}>
      {show === true && <Component />}
     </Permissions>
   }`

  Correct

 `{name === 'About' && show === true &&
   <Permissions allowed={'show'}>
     <Component />
   </Permissions>
  }`
