I’m trying to create a small app using Julia.  
This is the repo:

> **[GitHub - alvaradojl/julia-microservice: An example of a Julia microservice](https://github.com/alvaradojl/julia-microservice)**
>
> An example of a Julia microservice

I ventured into the packagecompiler.jl documentation, I tried to follow all the steps, unfortunately I get an error:

`$ julia --startup-file=no --output-o myapp.o -J"/opt/julia-1.4.2/lib/julia/sys.so" custom_sysimage.jl`

I’m using Ubuntu 18.04 and Julia 1.14:

`$ julia --v`  
julia version 1.4.2

`$ lsb_release -a`  
No LSB modules are available.  
Distributor ID: Ubuntu  
Description: Ubuntu 18.04.4 LTS  
Release: 18.04  
Codename: bionic

I also tried to create simple shared libraby (without the custom image)

```julia-auto
using MyApp
using PackageCompiler
create_sysimage([:MyApp];sysimage_path="sysimage_myapp.dylib")

```

and I also get this error

can you fix this error?

I can’t see `Dates` in [https://github.com/alvaradojl/julia-microservice/blob/master/Project.toml](https://github.com/alvaradojl/julia-microservice/blob/master/Project.toml)
