Cannot export datastore entity to Excel but can export datastore entity to Csv

Greetings,

I am having an issue with a!exportDataStoreEntityToExcel() but I do not have an issue with a!exportDataStoreEntityToCsv(). They use the same inputs.

I have uploaded a screenshot of the error message on the interface. I checked the tomcat-stdout log file and it says java.nullpointerexception. We are using a View on a PostgreSQL database.

I am not too positive but it might have stopped working after manually erasing some rows in the tables for the View.

We optimally want the Excel one working. Does somebody know what is wrong or have a similar issue?
