Hi Cris, what kind of error do you get? Could you please attach a screenshot? Thanks

HI Luzie - Thanks for your reply. This is the only error I see. 

Apex heap size too large: 6135427

There is a workaround but it involves using javascript.

Have you considered using standard Salesforce options? This is a lot of records for what seems outside core Skuid functionality. Exporting a screenful of records is more the target use for this functionality.

Thanks for the reply Pat! Yes, I built a Salesforce report for users as a workaround. 

Hey @Cris_Dawson !

Skuid has implemented a new export feature that allows you to customize the type of data you want to export in the new Chicago release. As always, the best practices for upgrading can be found in Upgrading Skuid on Salesforce.

As a reminder, Salesforce does NOT allow reverting back to prior versions of managed packages. Skuid always recommends installing new versions in a non-business critical sandbox environment to test all mission-critical functionality before installing into a production environment. We also recommend that you update out-of-date themes and design systems after you upgrade.

Please let us know if you continue to encounter any problems with this issue after upgrading.

Thanks,
