Seems like the MeteredInvocationHandleFactory in feign-micrometer 11.5 tries to create both a timer and counter with the same name when using a custom error
decoder that does not return a subclass of FeignException. This results in the following exception:
Caused by: java.lang.IllegalArgumentException: There is already a registered meter of a different type with the same name
