JavaScript api export to excel error

Prashanth Shenoy Apr 11, 2018 9:49 PM

Hi All,

We are facing an issue with one of our features post the upgrade to 10.5. Wanted to know if anyone has faced similar issue if so what was the resolution. Any help would be great... Thanks

We have embedded our dashboards in a JavaScript Portal. Post the upgrade to 10.5 our export data feature in the portal (we use the vizReports.showExportDataDialog() function) is not working.

We have an button in our portal that calls the vizReports.showExportDataDialog() to export the data. On clicking this, the Tableau data dialog comes up and then we get the error mentioned in the the case. Please refer the image attached 'Exportdataerror.jpg'

We get the below Tableau error :

An unexpected error occurred. If you continue to receive this error please contact your Tableau Server Administrator.

Session ID: 29EFB4F55C6349628DCF9491D1D621D5-0:1

Uncaught TypeError: tabBootstrap.ViewerBootstrap.get_instance(...).get_session,BeingCleared is not a function

Please note that it is working fine when trying directly on the Tableau Server.

We tried using the following JS API

https://public.tableau.com/javascripts/api/tableau-2.min.js

https://public.tableau.com/javascripts/api/tableau-2.2.1.min.js

Request you to please help us on this. Thanks

Regards,

Prashanth

Hello Prashanth,

I have asked internally but I believe this error is a known issue that will be resolved in the next release.

Thanks Patrick - I thought that it had been resolved with the release of 10.5.3 (according to Error "uncaught TypeError: tabBootstrap.ViewerBootstrap.get_instance(...).get_sessionBeingCleared is not a function" and… ) but we still seem to be encountering the issue after upgrading from 10.5.2. NOTE: Our issue is with Exporting to CSV only, and it appears that Export to Crosstab is working correctly (and least on the ones that I tested).

We have dashboards embedded in a portal, with a button coded to export a specified worksheet from each workbook as csv. I am finding that when I click on an actual sheet (to put the focus on it) the export button works, but the default code is failing after the upgrade to 10.5. I did open up a support ticket, but figured I would pass along the info.

Hi Jeff,

Thanks for the information. Actually the support team informed me the that this issue has been resolved in 10.5.3 though I have not had a chance yet to upgrade and check.

Please do let me know if you hear anything on the new ticket that you raised. Thanks

Hi Patrick,

Thanks, the support team did mention that. Also I read the reply from Jeff which seems to suggest that the issue has not been resolved in 10.5.3. Would wait for further update on this.
