Getting Error - "Username and Pool information are required" in Nest App When ChangePassword is Called

Question

I was Trying with NestJS and Cognito and Getting the below Error -

"message": "Username and Pool information are required."

The Controller I have Built is -

@Patch('changePassword')
  async changePassword(@Body() user: ChangePasswordDto) {
    try {
      return await this.authService.changePassword(user);
    } catch (e) {
      throw new HttpException(e.message, e.status);
    }
  }

The service for the change Password is -

changePassword(user: ChangePasswordDto) {
    const { username, oldPassword, newPassword } = user;
    const userData = {
      Username: username,
      Pool: this.userPool,
    };
    const cognitoUser = new CognitoUser(userData);
    cognitoUser.getSession((err: any, result: any) => {
      if (result) {
        cognitoUser.changePassword(
          oldPassword,
          newPassword,
          (err: any, result: any) => {
            if (result) {
              return result;
            } else {
              throw new HttpException(err, HttpStatus.INTERNAL_SERVER_ERROR);
            }
          },
        );
      } else {
        throw new HttpException(err, HttpStatus.UNAUTHORIZED);
      }
    });
  }

The User pool has been initialized at constructor like -

this.userPool = new CognitoUserPool({
    UserPoolId: this.authConfig.userPoolId,
    ClientId: this.authConfig.clientId,
});

I am able to successfully login and getting some Response like this -

Solved this By the Following Snippets -

Controller

@Post('changePassword')
  @UsePipes(ValidationPipe)
  async changePassword(
    @Body() authChangePasswordUserDto: AuthChangePasswordUserDto,
  ) {
    const result = await this.awsCognitoService.changeUserPassword(
      authChangePasswordUserDto,
    );
    if (result == 'SUCCESS') {
      return { status: 'Password Changed Successfully' };
    }
  }

Service

async changeUserPassword(
    authChangePasswordUserDto: AuthChangePasswordUserDto,
  ) {
    const { email, currentPassword, newPassword } = authChangePasswordUserDto;

    const userData = {
      Username: email,
      Pool: this.userPool,
    };

    const authenticationDetails = new AuthenticationDetails({
      Username: email,
      Password: currentPassword,
    });

    const userCognito = new CognitoUser(userData);

    return new Promise((resolve, reject) => {
      userCognito.authenticateUser(authenticationDetails, {
        onSuccess: () => {
          userCognito.changePassword(
            currentPassword,
            newPassword,
            (err, result) => {
              if (err) {
                reject(err);
                return;
              }
              resolve(result);
            },
          );
        },
        onFailure: (err) => {
          reject(err);
        },
      });
    });
  }

Also, Please make sure to make the changes in your User Pool in AWS to login with your email as username.
