When you start the application, an error occurs and the app crashes.

@splunk/otel v2.14.0 is using @opentelemetry/sdk-metrics v1.26.0

splunk-otel-js/package.json

Line 153 in c89f1a9

"@opentelemetry/sdk-metrics": "1.26.0",

The bug with PeriodicExportingMetricReader seems to be fixed in v1.27.0, v1.28.0.

Thanks, I've released 2.15.0 which is using sdk-metrics 1.28.0. Hopefully it resolves the issue, please reopen if you still see it.
