Unexpected union results

[brynrhodes]

The following union works as expected:

define Foo3: { 1 } union { 1.0 }

returning { 1, 1.0 }

However, this oddly results in a null?

define Foo2: { 1, 'hi', true } union { 1.0, true }

I expected { 1, 'hi', true, 1.0 } but I get { 1, 'hi', true, null }?

Appears that this may be a bug in the CQL Language Server rather than the CQL Runtime. IOW, they underlying value appears to be correctly computed, but it's serialized incorrectly.
