Flow cancellation shouldn't fail if there's a serialization errorDescriptionFlow cancellation is failing due to a serialization errorSteps to Reproduce Create a flow with a 'Wait for' condition.Execute the flow.Navigate to sys_json_chunk and delete or corrupt the data field for this flow.Cancel the flow. An exception will occur and it is expected. However, the record watchers are not cleaned up.WorkaroundTo cancel the flow manually, use GlideRecord to query the context and update the state field: var context = new GlideRecord('sys_flow_context');context.get('<sys_id>');context.state = 'CANCELLED';context.update();Related Problem: PRB1424373
