While running the FME script I am encountering the following error message :

No SCHEMA dataset name was specified (couldn't find a value for `SCHEMA_2_DATASET' or `SCHEMA_DATASET')

We have upgraded to new FME version 2021.2 from old fme version (2016).

The script is running fine on the old fme version but having some issues in the new FME version.

The script has multiple shape file parameters

The data set in the FME script code are in the following format :

#! <DATASET

#! NAME="SCHEMA_1"

#! OVERRIDE="-SCHEMA_1_DATASET"

#! DATASET="abc.shp"

#! />

#! <DATASET

#! NAME="SHAPE_1"

#! OVERRIDE="-SHAPE_1_DATASET"

#! DATASET="def.shp"

#! />

#! <DATASET

#! NAME="SCHEMA_2"

#! OVERRIDE="-SCHEMA_2_DATASET"

#! DATASET="ghi.shp"

#! />

#! <DATASET

#! NAME="SHAPE_2"

#! OVERRIDE="-SHAPE_2_DATASET"

#! DATASET="jkl.shp"

#! />

#! <DATASET

#! NAME="SCHEMA_3"

#! OVERRIDE="-SCHEMA_3_DATASET"

#! DATASET="mno.shp"

#! />

I am adding values of Project Name, Outline SHP ,Parcel SHP #1 and Attribute Name #1.

Remaining all values are NULL
