R[0] is undefined error while metadata export

Okay thanks! For now please try the following:

  1. Clear system cache by going to Data Administration app → Maintenance → Clear application cache and reload apps

  2. Clear browser cache using the browser cache cleaner app and just in case the cache isn’t clearing properly.

  1. To double check if it’s not a browser cache issue use another browser/profile which you’ve not accessed this site before, if you still see the error then it’s not a cache issue.

  2. If you did all the above, please open the Network tab (F12 → Network) in your browser devtools, and then click the option which shows the error, click on the red text (if there is any) in the network tab, and take a screenshot.

Thank you!
