Affected version : _v8.X on postgres database_ **Observed behaviour** This bug occurs when attempting to generate an iteration or campaign report, when the ‘Include issue details’ box is ticked. Occurs on postgres databases with the following logs: [squash-tm (1).log](/uploads/958addb3180d4e8fe2f567f608354d23/squash-tm__1_.log) _Note: does not seem to be due to the number of anomalies present in the iteration or the anomalies themselves._ **Expected result** Generation should occur, especially if the anomalies are accessible from the ‘Known anomalies’ anchor of the iteration.
