Crud repository query methods are not working with List<Enum> as a parameter.

[jakov222]

Hello,
I am trying to write a method which accepts List containing enum as a parameter in an interface extending ListCrudRepository<T, UUID>

T findByEnumType(List<EnumType> enums)

however, in the result exception is thrown:

Caused by: com.couchbase.client.core.error.InvalidArgumentException: Unsupported type for JSON value: class com.xxx.EnumType
	at com.couchbase.client.core.error.InvalidArgumentException.fromMessage(InvalidArgumentException.java:28)
	at com.couchbase.client.java.json.JsonValue.coerce(JsonValue.java:94)
	at com.couchbase.client.java.json.JsonArray.add(JsonArray.java:178)

Can you please look at the solution in #1837 ?

If that does not help, can you show your application and where it fails?

[jakov222]

I tested on 5.1.5 and it still doesn't work. I am not overriding any couchbase configuration. I am only having single ListCrudRepository bean, where all methods are working expect the one mentioned above. I will to provide mini project reproducing it in the coming days

There's a bigger stacktrace:

Yes. I never actually fixed it. I just provided a work-around. Sorry for sending you down that path.

I am not overriding any couchbase configuration.

That's the issue. Since you don't override it, you get one provided for you ... the couchbaseCustomConversions created in CouchbaseDataConfiguration does not have the Enum converters (I'll need to work with spring-boot-autoconfigure to fix that). The work-around in #1837 is to have the @configuration class extend AbstractCouchbaseConfiguration (see the last post in #1837).

[jakov222]

Alright, thank you! Is there a chance that the autoconfiguration fix will come anywhere soon?

[mikereiche]

The fix is merged into main. It will be in the next release which is scheduled for November 17. It will already be in the latest 5.2 SNAPSHOT. I'll merge it into the 5.1 and 5.0 branches to day and it will be in those SNAPSHOTS tomorrow. There is information in the doc how to get the SNAPSHOTs @jakubszybisty . I've used #1837 as the main issue for this, so you'll find more details there.
