Some paths listed in /download_formats dont return a file (or anything)

[Bud-Macaulay]

Documenting this even though it may be fixed in the future (or already fixed)

The API version that MaterialsCloud uses, some of the endpoints listed by:
/api/v4/nodes/download_formats
return a ISE- 500 error when hit.

for example:
https://aiida.materialscloud.org/2dtopo/api/v4/nodes/5f67654e-e9b4-4934-8aca-1a6816315b35/download?download_format=json
despite:
https://aiida.dev.materialscloud.org/mc2d/api/v4/nodes/download_formats
listing array data as json downloadable.

These should be cleaned up while maintaining the download_formats endpoint (or something similar) and I think there are plenty such examples

Thanks @Bud-Macaulay. I'm not sure I understand the issue here. Let's discuss next week if you're around.
