Linking to schemas in different yaml files

When I drop the following three files, I get the error:

Unhandled Rejection (TypeError): Cannot read properties of undefined (reading '../upload/raw/chemical_schema.archive.yaml')

I both upload the files and their content below:

CHEMICAL.archive.yaml

chemical_schema.archive.yaml

movpe_app-def_data.archive.yaml

definitions:
  name: 'Electronic Lab Notebook schema fot MOVPE-STO'
  sections:  # Schemas consist of section definitions
    MovpeSto_schema:  # This is the name of the first section
      # Inheriting it from EntryData, makes this section a possible
      # EntryArchive.data sub-section
      base_section: nomad.datamodel.data.EntryData
