"ORA-20987: Error at line 1, col 1: expected [ or {" -> when using REST Data Source in IG

Hi,
Using the great tutorial here: https://www.youtube.com/watch?v=4a9VxZjnT7E
I have setup a WEB API application running on a simple Department table (DepartmentId, DepartmentName).
I have also created a REST Data Source in APEX and added the PUT operation.
Then, I created a simple IG based on the REST Data Source.
Now, when I try to update (PUT) any of the values in the table, the method is actually executed (I can see the change in the underlying DB) but I also I get the following error:
ora_sqlerrm: ORA-20987: Error at line 1, col 1: expected [ or { error_backtrace: ORA-06512: at "APEX_200200.WWV_FLOW_INTERACTIVE_GRID", line 8425 ORA-06512: at "APEX_200200.WWV_FLOW_INTERACTIVE_GRID", line 8448 ORA-06512: at "APEX_200200.WWV_FLOW_PROCESS_NATIVE", line 1140 ORA-06512: at "APEX_200200.WWV_FLOW_PLUGIN", line 2757 ORA-06512: at "APEX_200200.WWV_FLOW_PROCESS", line 203 component: APEX_APPLICATION_PAGE_PROCESS Department - Save Interactive Grid Data (17097396615592433)
Note when testing the PUT method from POSTMAN - everything seems to be OK.

Found the cause... In my WEB API I was returning a string but APEX seems to be expecting an HTTP response.
So changed:
public string Put(Department dep)
{
try
{
string query = @"
update dbo.Department set DepartmentName=
'" + dep.DepartmentName + @"'
where DepartmentId="[email protected]"
";
DataTable table = new DataTable();
using (var con = new SqlConnection(ConfigurationManager.
ConnectionStrings["EmployeeAppDB"].ConnectionString))
using (var cmd = new SqlCommand(query, con))
using (var da = new SqlDataAdapter(cmd))
{
cmd.CommandType = CommandType.Text;
da.Fill(table);
}
return "Successfuly updated row!";
}
catch (Exception)
{
return "Could not update row!";
}
}
to
public HttpResponseMessage Put(Department dep)
{
try
{
string query = @"
update dbo.Department set DepartmentName=
'" + dep.DepartmentName + @"'
where DepartmentId="[email protected]"
";
DataTable table = new DataTable();
using (var con = new SqlConnection(ConfigurationManager.
ConnectionStrings["EmployeeAppDB"].ConnectionString))
using (var cmd = new SqlCommand(query, con))
using (var da = new SqlDataAdapter(cmd))
{
cmd.CommandType = CommandType.Text;
da.Fill(table);
}
return Request.CreateResponse(HttpStatusCode.OK, table);
}
catch (Exception)
{
return Request.CreateResponse(HttpStatusCode.NotFound, "Could not update row!");
}
}
Hope it helps someone!
