Question:
Cannot provision an actuator in IoT Agent Fiware

Description:
I am using the following python code to create a service group
import json
import requests

url = 'http://localhost:4041/iot/services'
headers =

data = {
"services": [

]
}
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 =

data = {
"devices": [
{
"device_id": "door003",
"entity_name": "urn:ngsi-ld:Door:door003",
"entity_type": "Door",
"protocol": "PDI-IoTA-UltraLight",
"transport": "MQTT",
"commands": [

,

,

,

],
"attributes": [

]
}
]
}

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:

Orion version:
{
"orion" : {
"version" : "2.2.0",
"uptime" : "0 d, 0 h, 59 m, 18 s",
"git_hash" : "5a46a70de9e0b809cce1a1b7295027eea0aa757f",
"compile_time" : "Thu Feb 21 10:28:42 UTC 2019",

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