connection.execute("JSON.MGET", args) not working as expected

[jochen-schuettler]

When we do

        List<byte[]> argList = new ArrayList<>();
        for (String key : keys) {
            argList.add(key.getBytes(UTF_8));
        }
        argList.add(".".getBytes(UTF_8));
        byte[][] args = argList.toArray(new byte[0][]);
        var result = connection.execute("JSON.MGET", args);

we get a Json array with one element, the result from the last key.

We expect results for all keys.

Hey @jochen-schuettler
Would you provide a little more information.

• Lettuce version
• Redis version
• Are you using Lettuce directly or some other upstream library ?

[jochen-schuettler]

Lettuce version: 6.6.0 <- I think, at least that is in our dep list
Redis container: redis:8-alpine -> 8.4.0
Are you using Lettuce directly or some other upstream library ? spring-data-redis:3.5.72

Thanks @jochen-schuettler .
There are some more questions actually - like what kind of deployment are you using for example (cluster, standalone ...). Also in the code snippet that you provided what does connection stand for ?
But most helpful will be if you are able to provide a minimum reproducible example, so we can investigate in detail. Can you provide it ?

[jochen-schuettler]

I will, yes. Takes some time to build a simple example with the same setup.

run the test should return more than the last key to show the problem
