interesting, i'm getting a slightly diff error:

DBG marketplace> fetched policy bundle from upstream policy=//assets.api.mondoo.app/spaces/beautiful-wiles-231755/assets/2fEbnpshR0sNpdZHMnbP8GbHnbC req-id=global
DBG client> got policy bundle
fatal error: runtime: out of memory

runtime stack:
runtime.throw({0x1ef6839?, 0x20300b?})

[vjeffrey]

which means we hit this first log message, but not the next

		log.Debug().Msg("client> got policy bundle")
		logger.TraceJSON(assetBundle)
		logger.DebugDumpYAML("assetBundle", assetBundle)
	}

	rawFilters, err := hub.GetPolicyFilters(s.job.Ctx, &policy.Mrn{Mrn: s.job.Asset.Mrn})
	if err != nil {
		return nil, err
	}
	log.Debug().Str("asset", s.job.Asset.Mrn).Msg("client> got policy filters")
	logger.TraceJSON(rawFilters)
	logger.DebugDumpYAML("policyFilters", rawFilters)

[vjeffrey]

this line appears to be the one i'm hitting: logger.DebugDumpYAML("assetBundle", assetBundle

but when i run without debug, it runs through just fine 🤔

@vjeffrey this was a t2.micro instance. Do you want me to try it with a t2.small or medium as well?
