Unable to get an error while using opsForHash().get() command

[MariaNosareva]

Hi,
I came across some strange behavior while working with ReactiveHashOperations: it seems that there is no error propagation in the case of getting value from hash by only one key (.get(key) method).

spring-data-redis/src/main/java/org/springframework/data/redis/connection/lettuce/LettuceReactiveHashCommands.java

Lines 109 to 110 in bae2eae

	result = cmd.hget(command.getKey(), key.duplicate()).map(value -> KeyValue.fromNullable(key, value))
	.map(Collections::singletonList).onErrorReturn(Collections.emptyList());

For example, if the service has trouble reconnecting to Redis, the endpoint user of that method will never know if any problems exist. But in the case of using .multiGet() (uses the same method under the hood - hMGet()) there is no such issue, all errors are delivered well.

Is there any chance of changing this behavior?

Thanks!

Thanks for reporting the issue. It is indeed a regression in which the empty response should return a collection with an empty element.
