But every time I try it comes up with a 500 error regardless of how many customers are included in the export.
Exporting sales works fine so it's not an error with exporting generally. I've checked the developer console and it comes up with a js error.
Looking in the logs I also found the following error message:
GET /myadmin/mui/export/gridToCsv/key/a07f4aed6c1179773233c13c4e984264d2309de49d34d35fe8580a8c42ca54cb/?filters%5Bplaceholder%5D=true&filters%5Bcreated_at%5D%5Bfrom%5D=02%2F01%2F2019&filters%5Bcreated_at%5D%5Bto%5D=02%2F07%2F2019&search=&namespace=customer_listing&selected=false HTTP/1.0
I'm not very experienced with Magento so I'm not sure what is causing this error. I'd appreciate some help to resolve this situation please.
