Topic: ✔ NullPointerException because "languages" is null

view this post on Zulip Juan (Nov 18 2024 at 10:35):

Hi, we are migrating e-cienciaDatos from Dataverse v5.10.1 to v6.4 and we get a null pointer exception in the languages Field.
It works in v5.10.1, but fails in v6.4

The database :Languages setting entry is filled.
dvndb=> select  * from setting where name =':Languages';
   name    |                                                content                                                 | id | lang  
------------+--------------------------------------------------------------------------------------------------------+----+------
:Languages | [{"locale":"es","title":"Spanish"},{"locale":"en","title":"English"},{"locale":"fr","title":"French"}] | 40 |  

The dataverse.lang .directory value in domain.xml file is set
grep dataverse.lang $PAYARA/glassfish/domains/domain1/config/domain.xml
       <jvm-options>-Ddataverse.lang.directory=/usr/local/dataverseLang</jvm-options>

The log trace is long, but we have checked that the Dataverse.initLocale method is called and all languages are read:
The server.log trace shows:

Do you know where could be the problem?

Thanks

@Juan yikes, thanks for letting us know. I see cvocConf.get in there. As an experiment, have you tried disabling the external controlled vocabulary feature?

Thanks @Philip Durbin 🐉 . I will try it.

I didn't have the ":CVocConf" entry in the database settings:

dvndb=> select * from setting where name like '%CVocConf%';
name | content | id | lang  
------+---------+----+------
(0 rows)

I think that the external vocabulary is disabled.

Thanks. Interesting. I wonder why it appears in the stacktrace.

According to https://metrics.dataverse.org eight installations have upgraded to 6.4 but I don't know if any of them are using multiple languages.

We aren't at Harvard Dataverse. Just English.

It looks like @Mireia Alcala replied already.

You are right, I will start with the Alfredo recommendation at first. Thanks.

At the end, the problem was that we were using a wrong Payara version. The help here and on the Google group was, as always, perfect.
