Rollup Designer doesn't work: `'pre_aggregations' must be a sequence`

[yiyu986]

Problem

Add to the Data Schema prompted "'pre_aggregations' must be a sequence", why?

Related Cube.js schema

main: {
  measures: [
    vm_gs_jbxx.count
  ],
  dimensions: [
    vm_gs_jbxx.clrq,
    vm_gs_jbxx.sfdm
  ],
  timeDimension: vm_gs_jbxx.clrq,
  granularity: `year`
}

  CAST(
    DATE_FORMAT(

    ) AS DATETIME

Thanks for reporting @yiyu986 🙌

This reproduces for me with Cube Core v1.6.6 when I try to add any pre-aggregation using Rollup Designer:
