Docker-machine cant mkdir on vmware datastore

Sending a docker-machine create command i get the error: Error creating machine: Unable to mkdir on datastore VMFS_DEV_001 due to Error: missing operand.

It looks like docker-machine is not sending (or i havn’t provided) one of the operand to govc but i have no idea and cant find anything in the docker-machine docs or in the govc documentation.
Here is a full command line output:

docker-machine -D create -d vmwarevsphere --vmwarevsphere-vcenter=“" --vmwarevsphere-username="” --vmwarevsphere-password=“" --vmwarevsphere-datacenter="” --vmwarevsphere-compute-ip="" --vmwarevsphere-datastore=“VMFS_DEV_001” --vmwarevsphere-disk-size=“20000” --vmwarevsphere-network=“VLAN710” test0109304shdsf
