BACKGROUND:

• De-serializing folders in tests broke recently because we started falling back to elements if something has an "Id" property, which folders do, but they are not Elements

DESCRIPTION:

• Check if there is a discriminator before falling back to Element or GeometricElement. non-elements can't fallback to these types even if they have an Id or Representation property.

TESTING:

• try to make/run a function that as a folder as an input. You will get a de serialization error on de serializing the input, then try with this change.

FUTURE WORK:

• NA

REQUIRED:

• All changes are up to date in CHANGELOG.md.

COMMENTS:

• Any other notes.

This change is
