I have the following issue:

transaction belongs to SentryEvent instead of SentryBaseEvent.
SentryTransaction extends SentryBaseEvent, so no environment is set.

https://docs.sentry.io/product/performance/distributed-tracing/#transactions

describes that environment and other fields should be part of the transaction.

Steps to reproduce:
enable tracing, set environment

Actual result:
transaction doesn't have environment field

Expected result:
transaction has environment field
