Makie：ERROR: MethodError: no method matching create_dim_conversion(::Type{Union{Missing, Float64}}) The function `create_dim_conversion` exists, but no method is defined for this combination of argument types

I upgraded Makie and the code that was working fine before started to give errors.
Has anyone encountered this problem? or Would it be better to go back to the previous version?

ERROR: MethodError: no method matching create_dim_conversion(::Type{Union{Missing, Float64}})
The function `create_dim_conversion` exists, but no method is defined for this combination of argument types.
Closest candidates are:

There are lots of this ways this could happen.
Can you open an issue with a minimal example how to reproduce the error?

@sdanisch
My confusion is that the same code and the same data were working properly before, but now they are causing an error.
Here is a test example.

I think it’s this issue:

In the calling side, adding the following fixes the issue. It works. Thanks for @sdanisch.

import Makie: create_dim_conversion

create_dim_conversion(union_typ::Type{Union{Missing,T}}) where {T<:Real} =
    create_dim_conversion(union_typ.b)

I encountered the error after upgrading from Makie 0.22 to Makie 0.24. I believe Makie should have fixed this bug.
