Certain Valid SBOMs fail on Conversion.

[txdvse]

Describe the bug
Some valid SBOMs that are uploaded to SBOM-in-a-Box fail when attempting to convert them. This shouldn't happen since the original SBOM matches the required elements to be uploaded to SBOM-in-a-Box.

To Reproduce
Steps to reproduce the behavior:

1. Use the SPDX SBOM attached to this card
2. Open SBOM-in-a-Box
3. Upload the SPDX SBOM
4. Select it and press the Convert button
5. In the pop-up, select CDX14 for 'format' and use any desired schema.
6. Select Convert in the pop-up window.

Expected behavior
The SBOM will not be converted. Reload the SBOM-in-a-Box client to confirm.
The following message was displayed in the terminal when attempting to convert the SPDX SBOM to a CDX14 SBOM.
