Fail to OPENROWSET insert geometry data from parquet

Hi!

I'm trying to insert geometry data (WKB) from a parquet file to a data base table. I manage to get it working for small geometries but it's failing for lager geometriers. Here is the code:

INSERT db.s.t 
  SELECT geometry::STGeomFromWKB(a.geom,1) 
    FROM OPENROWSET
    (
      BULK 'path_to.parquet',
      FORMAT = 'PARQUET',
      DATA_SOURCE = 's3_sorce'
    ) AS a

The failure:

String or binary data would be truncated while reading column of type 'VARBINARY(8000)'. Check ANSI_WARNINGS option.... 

Seems as if the geometry type is not recognized. Is there a way around this?
