When exporting CSV, fields which contain arrays do not export the data. The resulting CSV returns a blank/null data field. Would be helpful to be able to include this somehow.
Hi @hellojs, welcome to the forum! 
Could you share a screenshot of your current settings?
Here is how this is working on my end:
I'm exporting data using: utils.exportData(query1.data, "data.csv", "csv")
The exported file (shown on the first screenshot) does include the values in the array.
