Hi everyone,
I have seen 2 posts with same error but didn't find any solution that works for my case.
I have created a view, and a record type with data source is an expression rule that query data from the view. The rule will return me below data subset. When I check the record list, I can see data being presented without any error.
However, when I create a gridField based on my record type's data, I got this error. I checked and can verify that my data don't contain any duplicated row. Is there any other reason that I should look at?
Thank you,

hi mollyn126 could you please share the code snippet of your grid, I would help for better understanding. Is your primary key is Unique? Is your Primary Key accepts null Values?
