Hi, i've tried to upload a CKAN dataset, and haven´t been able to either save it or preview it. The only way that i'm able to save the dataset, is if I choose "Save without metadata". I also checked trying to use the dataset for a report, and it doesn't work either. I checked the logs while trying to save it in different ways, and it always says the same :
