Error when trying to call SAP HANA stored procedure from service side

I am trying to call a SAP HANA hdbprocedure from my service side using below code.

var con = ConLib.getHDBConnection();
var uploadStmt = con.loadProcedure("_SYS_BIC" , "procname");
var result = uploadStmt("samplefield1",  "samplefield2", {"DATA":[{"id1":"id_1001","id2":"id_2001","year_col":"2018"}, {"id1":"id_1002","id2":"id_2002","year_col":"2019"}]})

The procedure takes below paramaters as input.

PROCEDURE procname (
IN field1 VARCHAR(100),
IN field2 VARCHAR(100)
IN in_table_data "schema_name"."hdbdd_file_name.table_type"
){}

The in_table_data is defined as below in hdbdd_file_name.hdbdd file.

Type table_type {
id1 : String(100);
id2 : String(100);
year_col : String(4);}

I am getting below error when I call the procedure from my service side.

" Error occured in processRequest method $.hdb.Connection.executeProcedure: Parameter at  position 3 is not of type that can be processed "

Could you please suggest what needs to be changed either at the DB side or service side to fix this issue.

Thank you in advance.

I'm under the impression that the definition of the array in your calling statement is incorrect:

var result = uploadStmt("samplefield1", "samplefield2", {"DATA":[{"id1":"id_1001","id2":"id_2001","year_col":"2018"}, {"id1":"id_1002","id2":"id_2002","year_col":"2019"}]})

instead, try it like so:

var result = uploadStmt("samplefield1"
                      , "samplefield2"
            , [{id1: 'id_1001', id2: 'id_2001', year_col: '2018'}
             , {id1: 'id_1002', id2: 'id_2002', year_col: '2019'}]
                       )
