WARNING: too many parse errors error=904

Hi,

In the alert log of an Oracle 12.2 database I see a lot of this errors:

select distinct aa.owner, aa.package_name, aa.subprogram_id, aa.object_name, aa.overload, aa.argument_name, 

aa.position, aa.data_type, aa.data_length, aa.in_out, aa.type_name, aa.type_subname, aa.type_link, aa.type_object_type, aa.pls_type,

where aa.object_id = ap.object_id and ap.subprogram_id = aa.subprogram_id and aa.package_name = ap.object_name 

and aa.owner = :OWNER and aa.package_name = :PACKAGE
