Taxonomy import: Concept scheme associations not preserved during CSV->JSON->import workflow

[gheorghe-porohnea]

Bug Description

When exporting taxonomy to CSV, modifying it, converting back to JSON, and re-importing, all concept scheme associations are lost. Concepts are imported successfully but show empty "conceptSchemes": [] arrays instead of being associated with their parent concept scheme.

Steps to Reproduce

1. Export taxonomy using: contentful organization taxonomy-export --organization-id <ORG_ID> --format=csv
2. Modify the CSV file (add/edit concepts)
3. Convert CSV back to JSON format using a transformation script that properly sets conceptSchemes arrays
4. Import using: contentful organization import --organization-id <ORG_ID> --content-file taxonomy-import.json
5. Export again to verify: concepts show "conceptSchemes": [] instead of proper associations

Expected Behavior

Concepts should maintain their associations with concept schemes after import, showing proper references like:

"conceptSchemes": [{
  "sys": {
    "id": "contentTaxonomy",
    "type": "Link",
    "linkType": "TaxonomyConceptScheme"
  }
}]

Actual Behavior

All imported concepts have empty concept scheme associations:
"conceptSchemes": []

Environment

• Contentful CLI version: 3.8.8
• Node.js version: v23.11.0
• OS: macOS 14.5.0

Additional Context

• The import command reports success without errors
• New concepts are created successfully
• Existing concepts are updated successfully
• Only the concept scheme associations are lost
• The JSON transformation script correctly generates the conceptSchemes arrays before import
• This appears to be a CLI import issue rather than a data transformation issue

Workaround Needed

Currently looking for alternative approaches such as:

1. Using Management API directly to set associations
2. Different CLI commands that preserve associations
3. Alternative export/import workflows

Is this expected behavior or a bug? The documentation suggests associations should be preserved during import.
