Getting all Test Cycles Rest API

Hi,

I want to get all the Test Cycle with the REST API

# BASE URL for Zephyr for Jira Cloud
BASE_URL = 'https://prod-api.zephyr4jiracloud.com/connect'

# RELATIVE PATH for token generation and make request to api
RELATIVE_PATH = '/public/rest/api/1.0/cycles/search'

# QUERY STRING for API
QUERY_STRING = "versionId=1&projectId=10102"

# CANONICAL PATH (Http Method & Relative Path & Query String)
CANONICAL_PATH = 'GET&'+ RELATIVE_PATH  + '&' +QUERY_STRING

# TOKEN HEADER: to generate jwt token
payload_token = {
            'sub': ACCOUNT_ID,
            'qsh': hashlib.sha256(CANONICAL_PATH.encode('utf-8')).hexdigest(),
            'iss': ACCESS_KEY,
            'exp': int(time.time())+JWT_EXPIRE,
            'iat': int(time.time())
        }

# GENERATE TOKEN
token = jwt.encode(payload_token, SECRET_KEY, algorithm='HS256').strip()  #.decode('utf-8')
print(token)
# REQUEST HEADER: to authenticate and authorize api
headers = {
            'Authorization': 'JWT '+token,
            'Content-Type': 'application/json',
            'zapiAccessKey': ACCESS_KEY
        }

# MAKE REQUEST:
print(BASE_URL + RELATIVE_PATH + '?' + QUERY_STRING)
raw_result = requests.get(BASE_URL + RELATIVE_PATH + '?' + QUERY_STRING, headers=headers)

These are the results:

{
    "clientMessage": "Invalid Json",
    "errorCode": 151,
    "errorType": "ERROR"
}

Any ideas?
