MOI throws error with EAGO.jl

[jonasmac16]

I have tried using EAGO.jl with GalacticOptim.jl but it seems to run into a couple of errors.
The MWE:

using GalacticOptim
using EAGO
rosenbrock(x,p) =  (p[1] - x[1])^2 + p[2] * (x[2] - x[1]^2)^2
x0 = zeros(2)
p  = [1.0,100.0]
l1 = rosenbrock(x0, p)
f = OptimizationFunction(rosenbrock, GalacticOptim.AutoForwardDiff())
prob = GalacticOptim.OptimizationProblem(f, x0, p, lb = [-1.0,-1.0], ub = [1.5,1.5])

sol = solve(prob, EAGO.Optimizer());

The first error I get is the following:

ERROR: MathOptInterface.UnsupportedAttribute{MathOptInterface.VariablePrimalStart}: Attribute MathOptInterface.VariablePrimalStart() is not supported by the model.
Stacktrace:

It seems like it doesn't like the fact that an initial values being set. The MOI interface might need some additional checks such as if the chosen optimiser allows for initial values.

So if I comment out that section which sets the initial values https://github.com/SciML/GalacticOptim.jl/blob/2b657d2a2e1ce80547c54b4cbb4f468d2ee56bad/src/solve/moi.jl#L155-L157

A new error emerges:

This probably relates to following lines and associated functions but I don't fully understand the MOI syntax.
