Dear All,

I recently updated some of my Julia packages related to optimization as follows:

```julia
[4076af6c] ↑ JuMP v0.21.10 ⇒ v0.22.1
[b8f27783] ↑ MathOptInterface v0.9.22 ⇒ v0.10.6
[1ec41992] ↑ MosekTools v0.9.4 ⇒ v0.10.0
[4076af6c] ↑ JuMP v0.21.10 ⇒ v0.22.1
[b8f27783] ↑ MathOptInterface v0.9.22 ⇒ v0.10.6
[1ec41992] ↑ MosekTools v0.9.4 ⇒ v0.10.0

```

Now after updating, I am getting error solving a very simple SDP, which I was able to solve without any problem prior to my update. My mosek version is 9.3.10 (the latest). The SDP is as follows:

```julia
using JuMP, MosekTools, Mosek, LinearAlgebra

N = 3

model = Model(optimizer_with_attributes(Mosek.Optimizer))

# construct G ⪰ 0
@variable(model, G[1:N, 1:N], PSD)

@variable(model, F[1:N-1] >= 0)

A = [1 2 3; 4 5 6; 7 8 9]

b = [7;8]

@constraint(model, F'*b + tr(G) <= 0)

@objective(model, Min, sum(F) - tr(G))

optimize!(model)

p_star = objective_value(model)

G_star = value.(G)

F_star = value.(F)

```

The error I am getting is as follows:

```julia

MethodError: no method matching set_column_name(::Mosek.Task, ::MosekTools.MatrixIndex, ::String)

```

I have no idea what is going on. The code ran without any problem before updating. Any tips/suggestions regarding how to avoid this issue will be much appreciated.

This looks like a bug in MosekTools.jl. Please open an issue.

Yes, I have done that. Thank you @odow .
