Azure loganalytics python SDK always throws MissingApiVersionParameter exception

Question

I try to follow MS official doc to get the log from my resource in Azure Log Monitor but never success. My code is like below.

from azure.loganalytics import LogAnalyticsDataClient
from azure.common.client_factory import get_client_from_cli_profile
from azure.loganalytics.models import QueryBody

log_client = get_client_from_cli_profile(LogAnalyticsDataClient)

myWorkSpaceId = '1234567890...'
result = log_client.query(myWorkSpaceId, QueryBody(**{'query': 'Heartbeat| limit 50'}))

And I always get exception like below:

result = log_client.query(myWorkSpaceId, QueryBody(**{'query': 'Heartbeat| limit 50'}))
File ".../lib/python2.7/site-packages/azure/loganalytics/log_analytics_data_client.py", line 121, in query
raise models.ErrorResponseException(self._deserialize, response)
azure.loganalytics.models.error_response.ErrorResponseException: (MissingApiVersionParameter) The api-version query parameter (?api-version=) is required for all requests

I trace code into library in /azure/loganalytics/log_analytics_data_client.py, and dump the url string used for query like below.

print(url, query_parameters, header_parameters, body_content)
request = self._client.post(url, query_parameters)
response = self._client.send(request, header_parameters, body_content, stream=False, **operation_config)

The output of the url and query information is like below and it look like no version information in between and I doubt this is why I get the exception: ('https://management.azure.com/workspaces/1234567890.../query', {}, {'Content-Type': 'application/json; charset=utf-8'}, {'query': 'Heartbeat| limit 50'})

My azure SDK version is 4.0.0, and my azure-loganalytics library version is v0.1.0, running on Ubuntu. Does anyone run into same issue or know how to fix this?

Thanks.
