Margin cache generation fails for a catalog with a struct-list column

[hombit]

Bug report

I have parquet files produced by LSDB which contain nested column "lc" with four fields: mjd, mag, magerr, band. I successfully hats-imported those files. However I have a weird problem in margin pipeline which tells me that struct-fields are in a wrong order (truncated):

Failed REDUCING stage for pixel: 0_9
worker address: tcp://127.0.0.1:38957
struct fields don't match or are in the wrong order: Input fields: struct<band: list<element: string>, mag: list<element: float>, magerr: list<element: uint16>, mjd: list<element: double>> output fields: struct<mjd: list<element: double>, mag: list<element: float>, magerr: list<element: uint16>, band: list<element: string>>
