v.5.51.4#
Changes
- 
The ability to create a schedule for Estimator, Clustering, Exporter, Cross-matching, Roc-curve calculating and Additional extraction tasks has been added. When creating an Estimator task schedule, it is not possible to specify a ZIP archive as an image source. 
- 
A new series "Matching-Process" has been added to the monitoring of the Python Matcher service, containing information on the matching — time of matching, time of receiving the candidate from the database, etc. See the Python Matcher service developer manual for a list of all the fields and tags in the new series. 
- 
Request and error monitoring for the Lambda service has been added. See additional information in the Lambda service developer manual. 
Fixed errors
- 
Fixed the error where requests to the "/features" resource would fail with an "Internal server error" when using a perpetual license. 
- 
Fixed the error that caused the websocket connection to fail in some cases. 
- 
Fixed the error in the OpenAPI specification where redundant candidate types were displayed in the request bodies for "matching faces" and "human body matching". 
- 
Fixed the error that led to the "Internal server error" if an incorrect msgpack was passed in the request body "generate stream events" (request in beta testing state). 
- 
Fixed the error in which an error with the code "12022" with the description "message: 'filters.origin must be one of ['faces', 'events', 'attributes']" was returned in the response to the "human body matching" request containing various types of candidates and references in filters. Now the error does not contain a list of all types, but a specific type that should be specified in the filter.
