We have upgraded our dataverse from 4.7 to 4.10.1 and one of the users got an error today while creating dataset within a dataverse created with non-default metadata as attached below. when they tried to create a dataset within this dataverse it gave an error "Internal Server Error - An unexpected error was encountered, no more information is available." and the logs showed #{DatasetPage.init}: java.lang.NullPointerException but if you saved it with the default metadata settings and then change it, it works fine. Any idea why is that happening?

Hi Ahmed,

I'm sorry you're having this trouble. Thanks for the screenshot.

Can you please tell us (from server.log) which line of DatasetPage is throwing NullPointerException? It looks like it's somewhere in the "init" method so somewhere around here: https://github.com/IQSS/dataverse/blob/v4.10.1/src/main/java/edu/harvard/iq/dataverse/DatasetPage.java#L1341

The specific line number might give us some more clues. You are also welcome to email your server.log file to sup...@dataverse.org

Thanks,

Phil
