@antonsviridov-src , trying to spin this up locally in testing, I'm seeing the following error:

{"SeverityText":"ERROR","Timestamp":1739907970056237468,"InstrumentationScope":"conf.client","Caller":"conf/client.go:305","Function":"github.com/sourcegraph/sourcegraph/internal/conf.(*client).continuouslyUpdate","Body":"received error during background config update","Resource":{"service.name":"syntactic-code-intel-worker","service.version":"6.0.0","service.instance.id":"b7c572526148"},"Attributes":{"triggered_by":"waitForSleep","error":"unable to fetch new configuration: rpc error: code = Unavailable desc = connection error: desc = \"error reading server preface: http2: frame too large\""}}

Any ideas what might be the cause here? 🙏
