Cannot provision an actuator in IoT Agent Fiware - mqtt

Question

I am using the following python code to create a service group
import json
import requests
url = 'http://localhost:4041/iot/services'
headers = {'Content-Type': "application/json", 'fiware-service': "openiot", 'fiware-servicepath': "/mtp"}
data = {
"services": [
{
"apikey": "456dgffdg56465dfg",
"cbroker": "http://orion:1026",
"entity_type": "Door",
#resource attribute is left blank since HTTP communication is not being used
"resource": ""
}
]
}
res = requests.post(url, json=data, headers=headers)
#print(res.status_code)
if res.status_code == 201:
print("Created")
elif res.status_code == 409:
print("A resource cannot be created because it already exists")
else:
print (res.raise_for_status())
But when trying to provision an actuator I get a bad request 400 error with the code below:
import json
import requests
url = 'http://localhost:4041/iot/devices'
headers = {'Content-Type': "application/json", 'fiware-service': "openiot", 'fiware-servicepath': "/mtp"}
data = {
"devices": [
{
"device_id": "door003",
"entity_name": "urn:ngsi-ld:Door:door003",
"entity_type": "Door",
"protocol": "PDI-IoTA-UltraLight",
"transport": "MQTT",
"commands": [
{"name": "unlock","type": "command"},
{"name": "open","type": "command"},
{"name": "close","type": "command"},
{"name": "lock","type": "command"}
],
"attributes": [
{"object_id": "s", "name": "state", "type":"Text"}
]
}
]
}
res = requests.post(url, json=data, headers=headers)
#print(res.status_code)
if res.status_code == 201:
print("Created")
elif res.status_code == 409:
print("Entity cannot be created because it already exists")
else:
print (res.raise_for_status())
Here is the error message I get in console.

What is strange is that if a remove the commands from the payload the device provisioning works fine. Is there something am I doing wrong while trying to provision an actuator (not a sensor)?
IoT Agent version:
{"libVersion":"2.14.0-next","port":"4041","baseRoot":"/","version":"1.15.0-next"}
Orion version:
{
"orion" : {
"version" : "2.2.0",
"uptime" : "0 d, 0 h, 59 m, 18 s",
"git_hash" : "5a46a70de9e0b809cce1a1b7295027eea0aa757f",

"release_date" : "Thu Feb 21 10:28:42 UTC 2019",

}
}

depends_on:

Thanks in advance.
