Steps to reproduce

function initDynamoDBClient() {
  dynamoDBClient = new DynamoDBClient({
    region: "ap-east-1",
    credentials: {
      accessKeyId: AWSAccessKeyId,
      secretAccessKey: AWSSecretAccessKey,
    },
    endpoint: "https://dynamodb.ap-east-1.amazonaws.com",
  });
  const marshallOptions = {
    convertEmptyValues: false,
    removeUndefinedValues: false,
    convertClassInstanceToMap: false
  };
  const unmarshallOptions = {
    wrapNumbers: false
  };
  const translateConfig = { marshallOptions, unmarshallOptions };
  ddbDocClient = DynamoDBDocumentClient.from(dynamoDBClient, translateConfig);
  console.log("initDynamoDBClient finished");
}

async function updateHistoryItem(item) {
  const params = {
    TableName: tbName,
    Key: {
      url: item.url,
    },
    ExpressionAttributeValues: {
      ":read_state": item.read_state || 0,
      ":title": item.title,   //title is a string , include emoji.
    },
    UpdateExpression: `SET 
    title = :title,
    read_state = :read_state`,
  };
  return updateItemFromDynamoDB(params);
}

async function updateItemFromDynamoDB(params) {
  return sendCommandToDynamoDB(new UpdateCommand(params));
}

async function putItemFromDynamoDB(params) {
  return sendCommandToDynamoDB(new PutCommand(params));
}

async function sendCommandToDynamoDB(command) {
  try {
    const data = await ddbDocClient.send(command);
    console.log("AWS DynamoDB send command -- succeeded");
    return data;
  } catch (err) {    
    console.error(
      "AWS DynamoDB send command -- failed:" + "\n" + JSON.stringify(err)
    );
    return null;
  }
}

Observed behavior

Exception was thrown

Expected behavior
