kiota uses too much memory generating the msgraph beta go sdk

I'm running on a linux machine with 32GB, of which at least 28GB was available.

I ran:

hidi transform -d https://raw.githubusercontent.com/microsoftgraph/msgraph-metadata/master/openapi/beta/openapi.yaml -c msgraph.json -o output.yaml
kiota -l go -d output.yaml -c GraphServiceClient -n msgraphbetasdkgo  -o client --ll Trace

where msgraph.json is from https://gist.github.com/jaym/6cbb56b2405274bd169d76b2d4afb3f0

When kiota runs, it dies after a minute or so because it gets SIGKILL'd for using up all the memory:

fish: Job 1, 'kiota -l go -d output2.yaml -c…' terminated by signal SIGKILL (Forced quit)

dmesg shows the reason:

[1149689.168193] Out of memory: Killed process 3477026 (kiota) total-vm:38182588kB, anon-rss:26873152kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:54136kB oom_score_adj:0

Here's the tail of the output. There are a lot more of those not found warnings:
