Querying Redshift Serverless by Nodejs Getting permission issue.

I am encountering the following error while running my Node.js application to retrieve data using AWS Redshift Serverless. "'ERROR: permission denied for relation dashboard_view_product_sales_rank'," Here is my code below

    const redshiftDataApiClient = new AWS.RedshiftData({ region: 'eu-west-1' });

    const executeStatementInput = {
      WorkgroupName: 'workspace',
      Database:  'dev',
      Sql: getRedshiftSqlQuery()
    };
    const data = await redshiftDataApiClient.executeStatement(executeStatementInput).promise();

    const describe = await redshiftDataApiClient.describeStatement({ Id: data.Id }).promise();

    const result = await redshiftDataApiClient.getStatementResult({ Id: data.Id }).promise();

    return OK(result);
