The data order does not match the order downloaded from Tableau.

Worksheet.getSummaryDataReaderAsync() returns incorrect columns.order metadata

Summary

When using Worksheet.getSummaryDataReaderAsync() in Tableau Embedding API v3, the columns object includes an order property intended to represent the column sequence. However, this property does not match the actual column order in the worksheet or the order returned by getSummaryDataAsync. This leads to misleading metadata for consumers expecting accurate column positioning.

Environment

API: Tableau Embedding API v3 (@tableau/embedding-api
Server: Tableau Server/Cloud
Methods:Worksheet.getSummaryDataReaderAsync() → DataTableReader

Steps to Reproduce

• Embed a view with a known column order (e.g., Category, Sales, Profit).

Call

const reader = await sheet.getSummaryDataReaderAsync();  
const page = await reader.getPageAsync(0);  
console.log(page.columns);

Compare columns.order values with:

• The actual column sequence in the worksheet
• The order returned by getSummaryDataAsync()

Observe mismatch

columns.order does not reflect the real column order.Expectedcolumns.order should accurately represent the column sequence as displayed in the worksheet or documented as undefined.

Actual

columns.order is incorrect and misleading.
