[BUG]: Data contract file upload fails when the contract contains support entries

[GFernie]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Uploading a data contract file through the UI fails when the contract contains a support section.

I reproduced this in the Ontos UI using a minimal public ODCS example. Uploading the YAML file via Data Contracts -> Upload File returns 500 with {"detail":"Upload failed"}.

Audit log for the same failure shows:

TypeError: 'type' is an invalid keyword argument for DataContractSupportDb

The same file upload path succeeds when the contract does not contain support.

Additionally, after upload attempts the frontend throws Uncaught ReferenceError: Loader2 is not defined.

Expected Behavior

Uploading a valid ODCS contract file should import the contract successfully, including contracts that contain a support section.

Steps To Reproduce

1. Open Ontos and go to Data Contracts.
2. Click Upload File.
3. Upload this minimal YAML:

kind: DataContract
apiVersion: v3.1.0
id: urn:datacontract:example:public:upload:repro
name: public_support_upload_repro
version: 1.0.0
status: draft
description:
  purpose: Minimal public repro for Ontos contract upload failure.
support:
  - channel: "#support-example"
    tool: slack
    scope: technical
    url: https://example.com/support-example

4. Observe that POST /api/data-contracts/upload returns 500 and the upload fails.

Control comparison:

5. Upload this minimal YAML without support:

kind: DataContract
apiVersion: v3.1.0
id: urn:datacontract:example:public:upload:control
name: public_upload_control
version: 1.0.0
status: draft
description:
  purpose: Minimal public control contract without support entries.

6. Observe that POST /api/data-contracts/upload returns 200 and the contract is created successfully.
