Unable to write dumpcap output to mounted drive

I managed to automount an exFAT drive with rw permissions. The mount point is a directory I made (/media/usb1) and the drive itself is named usb1.

-shell
sudo dumpcap -i eth1  -w /media/usb1/logs -b duration:600 -b  files:100

Yet I get this error when running:

dumpcap: The file to which the capture would be saved could not be opened: No such file or directory.

I suspect the issue is specifically with writing to the external drive, but this code worked for a while before it seemed to arbitrarily stop. I'm looking over other resources but I can't find anything related to this specific issue.
