Issue using the DBFS PL/SQL API

Question

Hi guys,
I'm trying to use the DBFS PL/SQL APIs and create some simple functions that for example return the file size or move a file to a different path. I created a user DBFS_USER and granted DBFS_ROLE to that user. Using SQLDeveloper, when I run the following code, it works fine:
SET SERVEROUTPUT ON
DECLARE
l_props DBMS_DBFS_CONTENT_PROPERTIES_T;
l_prp dbms_dbfs_content_property_t;
l_blob BLOB;
l_item_type INTEGER;
BEGIN
DBMS_DBFS_CONTENT.getPath (
path => '/staging_area/test_dir/IAMDBFS_USER.txt',
properties => l_props,
content => l_blob,
item_type => l_item_type);
FOR x in 1..l_props.count LOOP
l_prp := l_props(x);
if (l_prp.propname = 'std:length') then
DBMS_OUTPUT.put_line(l_prp.propname || ' : ' || l_prp.propvalue);
end if;
END LOOP;
END;
However, when I try to put it in a package, I get the error message "Error(415,10): PLS-00201: identifier 'DBMS_DBFS_CONTENT_PROPERTY_T' must be declared" while trying to compile. This is what my package and its body looks like:
create or replace
PACKAGE MY_DBFS_PKG IS
Function GetFileLength
(P_FILE_PATH IN Varchar2
,P_ErrMsg OUT Varchar2)
Return Number;
END MY_DBFS_PKG
Body:
create or replace
PACKAGE BODY MY_DBFS_PKG IS
FUNCTION GetFileLength(
P_FILE_PATH IN VARCHAR2 ,
P_ErrMsg OUT VARCHAR2)
RETURN NUMBER
IS
l_return NUMBER;
l_props DBMS_DBFS_CONTENT_PROPERTIES_T;
l_prop DBMS_DBFS_CONTENT_PROPERTY_T;
l_blob BLOB;
l_item_type INTEGER;
BEGIN
l_Return := 0;
P_ErrMsg := NULL;
DBMS_DBFS_CONTENT.getPath ( path => p_file_path, properties => l_props, content => l_blob, item_type => l_item_type);
FOR x IN 1..l_props.count
LOOP
l_prop := l_props(x);
IF (l_prop.propname = 'std:length') THEN
l_Return := l_prop.propvalue;
EXIT;
END IF;
END LOOP;
EXCEPTION
WHEN OTHERS THEN
l_Return := NVL(SQLCODE, -1);
p_ErrMsg := SQLERRM;
RETURN l_return;
END GetFileLength;
END MY_DBFS_PKG;
Am I missing an extra grant somewhere? Or have I missed a declaration in the package or package body?
I am not a DB person so pardon the probably inefficient loop to find the length or wrong declaration somewhere. I'm open to suggestions/recommendations but want to use the DBFS PL/SQL API as I need other functions out of it.
Thanks very much in advance.
