Understand why `request.uri` and other agent attributes on Transactions are not ingested into New Relic

[kaylareopelle]

An internal user of the New Relic Ruby agent discovered the request.uri agent attribute not available on transactions queried in the New Relic UI. After looking at the agent's audit logs for the same transaction, the request.uri attribute was present in the agentAttributes payload. This behavior can be reproduced on a minimal Rails application.

In addition, request.parameters.id was also dropped. However, other request.* parameters, like request.headers.accept were preserved.

This behavior does not seem to be consistent across all language agents and some other languages are accurately ingesting the request.uri attribute.

Investigate the problem with internal teams to determine where in the ingest process the attribute is dropped.

See initial thread (internal) for details.
