Expensive logging

I work in a GCP environment and due to reportedly hideously expensive logging costs, I'm being told to cut down on logging. I believe in logging errors, but now we take a Java exception and report that XYZ exception occurred. No stack trace.

Tragically, this code will be deployed to production, leaving some poor support person the unenviable task of guessing where and why the exception occurred.

How are modern corporate apps doing logging given the unaffordable cost of logging? Please note, our current logging is going to GCP log explorer. The multi billion dollar corporation cannot afford to log, at least to gcp log explorer.
