Change in SummaryDataAsync when no data in sheet behavior changed

[merlijnbuit]

Hi guys,

Below piece of code was working perfect until recent updates to the extensions API. This behavior is taking place on Tableau Server and not on Desktop.

What we discovered recently?
When there is no summary data found in the sheet we normally would get an object with rows (0) and columns (0) meaning there is no data found in the sheet. But now we do not get anything anymore resulting in a crash and very ugly error message on server when certain filters or dashboard actions result in a empty sheet (which provides data to the extension). The 'then' in below example is not returning a single thing.

return settings.selectedSheet .getSummaryDataAsync() .then(({ columns, data: rows }) => { if (columns.length === 0 && rows.length === 0) { throw new Error( "Summary data is empty. A filter is probably excluding all data." ); } });

Can you have a look at this please?

Following this thread.

No data in the datasheet is not an error and can be a planned action. That's why we created a humane message. Throwing an error confuses the dashboard users.

Hi @merlijnbuit & @SiebeG
This was a result of our moving to the new object model implementation inside Tableau. While the object model provides awesome advantages, we have found two issues in the implementation.

1. getSummaryData fails when there is no data
2. getSummaryData has a limit of 10,000 rows

The first issue (no data error) was fixed in Tableau 2020.2.2. @merlijnbuit - can you check your server version?
The second issue (10k limit) will be fixed in 2020.2.4, which will be released later this month.

Let us know if you have any questions.
Thanks!
John

Hi @johnDance,

Thank you for your reply, really appreciated.
The error (instead of the message) when no data is available persists on Tableau Online (which is in our case version 2020.2.0)

When there is data:

@SiebeG - Thank you for the clarification. I did some research and found that the fix didn't get integrated into online until the 2020.3 staging. That is coming out soon. Sorry for the confusion. I'll update the fixes and timeline here:

getSummaryData fails when there is no data has been fixed in:

• desktop: 2020.2.2
• on-prem: 2020.2.2
• online: 2020.3

getSummaryData has a limit of 10,000 rows has been fixed in:

• desktop: 2020.2.4
• on-prem: 2020.2.4
• online: 2020.3

Hi @johnDance thank you for the update, really appreciated.

I can confirm the fix for getSummaryData fail when there is no data is working in 2020.2.3 (not able to test on 2020.2.2).

@johnDance still on track for releasing the bug fixes this month? A lot of customers are experiencing problems with the 10K issue as their analytics has become less valuable.

Hi @benlower,

I hope this message is received in good health for you and your loved ones. Can you confirm the updates are released in version 2020.2.4 (Desktop & Server) and 2020.3 (Online) and release date is in July as stated before in this thread by @johnDance ?

A lot of our customers are experiencing issues because of the 10K limit on summary data trasnfers by the Extensions API

Regards Siebe

@SiebeG , Yep the fix is in all of the next releases: 2020.2.4, 2020.3 Online and my understanding is that those will be released in July but that is pending all of the end-of-the-game activities that the release team does.
