Ok, I fixed this issue by simply removing PrometheusMeterRegistry bean from
config:
@Bean
@Primary
public PrometheusMeterRegistry meterRegistry() {
return new PrometheusMeterRegistry(PrometheusConfig.DEFAULT);
}
By removing the manual *PrometheusMeterRegistry* bean definition, Spring
Boot's auto-configuration handles the creation and wiring, which ensures
*/actuator/prometheus* works as expected.
