similar(::JuMP.Containers.DenseAxisArray...) is ambiguous

[baggepinnen]

The following snippet produces an ambiguity error from the last statement (JuMP v0.21.3, julia v1.5-rc1)

using JuMP, SCS
model = Model(SCS.Optimizer)
n = 10
V = randn(n,n)
@variable(model, G[n, n])
B = V*G*V'

MethodError: similar(::JuMP.Containers.DenseAxisArray{VariableRef,2,Tuple{Int64,Int64},Tuple{Dict{Int64,Int64},Dict{Int64,Int64}}}, ::Type{GenericAffExpr{Float64,VariableRef}}, ::Tuple{Int64,Int64}) is ambiguous. Candidates:

Sorr, my bad. I had the wrong syntax in creating the variable, it should be

@variable(model, G[1:n, 1:n])
