query errors when specifying parameters

[slwu89]

query errors when specifying the parameter (ID of a certain object) when using a union type for an AttrType in the following schema. On Catlab v0.16.17.

using Catlab

@present MySch <: SchGraph begin
    (P,PV,S)::Ob
    Label::AttrType
    vlabel::Attr(V,Label)
    plabel::Attr(P,Label)
    Number::AttrType
    pv_number::Attr(PV,Number)
    s_number::Attr(S,Number)
    pv_v::Hom(PV,V)
    pv_p::Hom(PV,P)
    s_e::Hom(S,E)
    s_p::Hom(S,P)
end

@acset_type MyDataType(MySch, index=[:src,:tgt,:pv_p,:pv_v,:s_p,:s_e])

mydata = @acset MyDataType{String,Union{Float64,Int}} begin
    V=5
    vlabel="v" .* string.(1:5)
    E=9
    src=[1,1,1,2,2,2,3,3,4]
    tgt=[2,3,4,1,3,5,1,2,1]
    PV=10
    pv_p=[1,2,1,2,1,2,1,2,1,2]
    pv_v=[1,1,2,2,3,3,4,4,5,5]
    pv_number=rand([1,2,3],10)
    P=2
    plabel="p" .* string.(1:2)
    S=16
    s_p=[1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2]
    s_e=[1,2,3,4,5,6,7,8,9,1,3,4,6,7,8,9]
    s_number=rand([5,6.0,7],16)
end

query_uwd = @relation (v=vlab, v_id=v_id, p=plab, p_id=p_id, s_number=s_number) begin
    PV(_id=pv_id, pv_p=p_id, pv_v=v_id)
    P(_id=p_id, plabel=plab)
    V(_id=v_id, vlabel=vlab)
    E(_id=e_id, tgt=v_id)
    S(_id=s_id, s_e=e_id, s_p=p_id, s_number=s_number)
end

# queries when `Number` is a `Union{Float64,Int}`
query(mydata, query_uwd) # works
query(mydata, query_uwd, (v_id=1, )) # error
query(mydata, query_uwd, (s_number=5, )) # works

Alas, I guess this was not fixed in #923?

I'm not sure @epatters, in this case, the error occurs when specifying the parameter of a part ID, rather than when using the parameters to specify attributes (which is weird). But in any case, I'll check it out in detail when I have time, making a note of the behavior here.
