Describe the bug

Using package @aws-sdk/client-cognito-identity-provider in a react native application.

Currently on version 3.654.0, all commands work with nil issues.

Patched to 3.686.0 which seems to be a breaking change on multiple commands. Two that I have tested are GetUserCommand and ConfirmForgotPasswordCommand.

I get breaking error

[TypeError: stream.arrayBuffer is not a function (it is undefined) Deserialization error: to see the raw response, inspect the hidden field {error}.$response on this object.]

Revert to 3.654.0 and all commands work again, nil issues.

Reproduction Steps

export const confirmForgotPassword = async (
  username: string,
  confirmationCode: string,
  newPassword: string
) => {
  try {
    const input = {
      ClientId: USER_POOL_WEB_CLIENT_ID,
      Username: username,
      ConfirmationCode: confirmationCode,
      Password: newPassword,
    };

    const command = new ConfirmForgotPasswordCommand(input);
    const response = await cognitoClient.send(command);

    return response;
  } catch (error) {
    console.error(`confirmForgotPassword error: `, error);
  }
};``

and the other one

const handleGetUserCommand = async (accessToken: string) => {
  try {
    const command = new GetUserCommand({
      AccessToken: accessToken,
    });
    const response = await cognitoClient.send(command);
    return response;
  } catch (error) {
    console.log(`handleGetUserCommand error: `, error);
    return null;
  }
};

Observed Behavior

Nil changes to code but when patched get the following breaking error

[TypeError: stream.arrayBuffer is not a function (it is undefined) Deserialization error: to see the raw response, inspect the hidden field {error}.$response on this object.]

Expected Behavior

Not break

Possible Solution

No response

Additional Information/Context

Try adding a polyfill for Blob.arrayBuffer().
