WSO2AM analytics 2.1 - null value in column “os” violates not-null constraint

问题

using WSO2AM 2.1 with analytics (I believe version 2.1 too) we have following exceptino in the aalytics' server log:

ERROR: null value in column "os" violates not-null constraint

Caused by: java.sql.BatchUpdateException: Batch entry 4 INSERT INTO API_REQ_USER_BROW_SUMMARY (api, version, apiPublisher, tenantDomain, total_request_count, year, month, day, requestTime, os, browser) VALUES ('agenda.city', '0.0.1', 'admin', 'carbon.super', 153, 2017, 8, 15, 1502794641000, NULL, NULL) ON CONFLICT (api,version,apiPublisher,year,month,day,os,browser,tenantDomain) DO UPDATE SET total_request_count=EXCLUDED.total_request_count, requestTime=EXCLUDED.requestTime was aborted: ERROR: null value in column "os" violates not-null constraint
  Detail: Failing row contains (agenda.city, 0.0.1, admin, carbon.super, 153, 2017, 8, 15, 1502794641000, null, null).  Call getNextException to see other errors in the batch.

As a note - I don't see a problem having null os or browser as not all clients (mainy backend API clients) may/will provide additional information

Edit (18.8.2018):

I see this exception doesn't occur on every environment, so the difference must be somewhere else (reused DB after upgrade from 2.0.0?), seems there are factors I am not aware of

As well I see te long always mention "Batch entry 38 ..", maybe I could just clean up the entries for the start. How do I do that?

This is already fixed [1] and will be available in the next release.
