An error occurred: Error fill report: Erro fill internal: java.lang.ExceptionInInitializerError Usually, this happens when it fails to populate the report according to the data from the data source. Does the database exist? Does the query table specified in the report exist in the database, along with its fields?

Will be closing soon due to lack of engagement.
