key.list() or .gen() always throw io.ipfs.cid.Cid$CidEncodingException: Invalid cid bytes

Hi all,

I'm trying to use the library to manage some files into ipfs. I've ipfs desktop installed and running. I can add files from java without any problem but i need to crate new key for ipns names because some files can be updated and I need a unique esternal name to retrieve the last and most updated version. When I try to call any ipfs.key.* method I always get the exception in title. What I'm doing wrong? (could not find any solution online) Here is my code:

` IPFS ipfs = new IPFS("/ip4/127.0.0.1/tcp/5001"); NamedStreamable.ByteArrayWrapper file = new NamedStreamable.ByteArrayWrapper(userId, text.getBytes()); MerkleNode addResult = ipfs.add(file).get(0);

        List<KeyInfo> keys = ipfs.key.list(); // exception here
        System.out.println("Keys: "+keys);

        Optional<String> keyType = Optional.of("rsa");
        Optional<String> keySize = Optional.of("2048");
        KeyInfo key = ipfs.key.gen(userId, keyType, keySize); // exception here (if I comment list() call.

        Map result = ipfs.name.publish(addResult.hash, Optional.of(key.name));
        System.out.println("IPNS: "+result);
        return result.get("Name");

` Thank you for you're help.

Just for information, trying to generate key on same name raises another exception of key existence, so the key generation seems to work but the conversion of the code attached to exception after "Invalid cid bytes" fails.

Updating java-cid library to last pull-request seems to solve problem.
