aws-sdk module installation errors in angular ionic project.

Can anyone help me resolve the errors due to the installation of aws-sdk module. npm i aws-sdk

import * as AWS from 'aws-sdk';

getAWSAccess(){
    const cognitoUser = this.userpool.getCurrentUser();
    AWS.config.region = 'us-east-1'
    return new Promise((resolve, reject) => {
      cognitoUser?.getSession((error:Error, result:any)=> {
        if (result) {
          // Add the User's Id Token to the Cognito credentials login map.
          AWS.config.credentials = new AWS.CognitoIdentityCredentials({
            IdentityPoolId: 'us-east-1:39c683dc-c454-426c-a3c4-b8c425447c18',
            Logins: {
              'cognito-idp.us-east-1.amazonaws.com/us-east-1_9lAFiKAxg': result.getIdToken().getJwtToken()
            }
          });
        }
      });
    }
    )
