novaClient.servers.create call fails with block_device_mapping_v2 option

[john Z]

I was able to create an instance with CLI
$ nova boot --flavor gc1.small --image c85b0898-2bbd-46be-8950-3c031f07cb93 --key-name dev_key --block-device id=c85b0898-2bbd-46be-8950-3c031f07cb93,source=image,dest=volume,type=disk,device=vda,size=30,bootindex=1,shutdown=remove --availability-zone dev_zone --security-groups dev_tech --nic net-id=6fc22c46-b895-408f-b005-b2c4de916d8c ins_from_cl

However, when I run code via Python API:
net = novaClient.networks.find(label='dev_net')
image = novaClient.images.find(name='Base RHEL 6.7 Cloud')
flavor = novaClient.flavors.find(name='gc1.small')
dev_mapping = [{ 'source_type' : 'image', "image_id" : image.id, 'device_name' : 'vda', "volume_id" : "f7c90ef0-925d-4c19-b499-a951793d7572", "volume_size" : 30, "boot_index" : 1, 'destination_type' : 'volume'}]
novaClient.servers.create('ins_from_python', image,flavor , key_name = 'dev_key' ,block_device_mapping_v2 =dev_mapping, availability_zone ='dev_zone', nics = [{'net-id': net.id}])

I got the following error:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr/share/lib/python2.7/site-packages/novaclient/v2/servers.py", line 995, in create *boot_kwargs)

And I noticed the a new item was added to dev_mapping list. I tried with "boot_index":0, it still failed.

I am using python-novaclient (2.35.0) with Python 2.7.9.
