Show the full error, and show where you're calling the export, you've probably not configured properly.

If you're using ESX and you have Config.ESX enabled then this will fetch your job, if it doesn't use a different version of ESX. If it still doesn't work then you're out of luck because OP doesn't check this repo if somebody PR's a fix.
