ORA-39126 when attempting expdp with network_link

Question

I'm trying to use expdp to get a dump of a db on another box so I can duplicate it on my dev machine.
I created a network link using :
create public database link preprodlink connect to "TESTUSER" identified by "testpass" using '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=my.machine.eu)(PORT=1521)))(CONNECT_DATA=(SID=PREPRODSID)))';
I have verified that this seems ok by doing :
select * from dual@preprodlink;
which runs successfully.
I then created a local user to match the schema with :
create user TESTUSER identified by testpass;
grant all privileges to TESTUSER;
I then attempt to do the actual export using
expdp TESTUSER/testpass directory=oratmp network_link=preprodlink dumpfile=TESTUSER.dmp schemas=TESTUSER exclude=statistics
But I get error ORA-39126 and PLS-00201.
I can't figure out what the problem is.
Full export log is below :

Answer 1

Oh well,
SQL> desc dbms_metadata
FUNCTION ADD_TRANSFORM RETURNS NUMBER
....Other than that, the point was what Dean says; check remote db (invalid packages, etc.). Involve remote db's dba. Is it possible to run export db locally on the remote db?
For invalid objects, try something like
select object_name, object_type from dba_objects where status != 'VALID';
