Error Incremental refresh from HDFS using CONVERT_FROM(JSON)

Hi,
i have an error trying to refresh in incremental mode a reflection on a VDS.
If i define a raw reflection on this vds it ends with no error, this is the profile:
9f7b16b7-86e9-42ac-8cbf-c6a77f04de55.zip (36,9 KB)
but if i try to refresh using the “refresh now” button on the pds configuration window, i recive the error:
Using CONVERT_FROM(*, ‘JSON’) is only supported against string literals and direct table references of types VARCHAR and VARBINARY.
the profile below.

Does anyone can help me please? :tired_face:
