That error is not from the PDF parsing, it's from using the _default (schemaless) schema. As the startup message says, schemaless mode is not recommended for production because it's impossible to guess right every time.
So I'd start with a schema that does not do this, see the reference guide section "schemaless mode", and "managed schema" and also the section of "classic" schemas...
