Mass DocGen button error

[rachel_lee]

I'm using Nintex DocGen version 17.1. We have a custom 'Mass DocGen' list button on the standard Opportunity object. It was configured just as described in this post: https://community.nintex.com/t5/How-To-s/Drawloop-Create-Mass-Button-in-Lightning/ta-p/92630

When we try to use this button from an Opportunity list view, no matter how many records we select, we get this error "Please select at least one record". Does anyone know why this would happen? Did we miss an update somehow?

Thanks.

I had this same error. I edited the Custom button and there was a new option under "Display Type" and "List Button" called "Display Checkboxes (for Multi-Record Selection). Once I checked that box it worked as it had before.
