[UBI] Fix Analytics backend handlers

Reporters

• Georgios P. Katsikas

Description

Analytics backend to date has two data handlers which appear to be invoked in a problematic way. Data to Kafka is not dispatched correctly.

TFS deployment settings

• context, device, service, pathcomp, telemetry, kpi*, analytics, policy, automation

Sequence of actions that resulted in the bug

• Call of the StartAnalyzer() RPC results in crashed handlers.

Expected behaviour

• After the fix, the aggregation handlers shall correctly write data in Kafka.
