ue4-docker: Failed to get CEF3 DLL handle

Output of the ue4-docker info command:

ue4-docker version:         0.0.38 (latest available version is 0.0.38)
Operating system:           Windows Server 2019 Datacenter Evaluation Version 1809 (OS Build 17763.379)
Docker daemon version:      19.03.3
NVIDIA Docker supported:    No
Maximum image size:         200GB
Available disk space:       374.14 GiB
Total system memory:        19.53 GiB physical, 35.29 GiB virtual
Number of processors:       10 physical, 20 logical

I’m using the docker images I build from a CI pipeline.

I have 2 different jobs, both of them with the same error.

The first job just executes:

ue4 test --all

The second instead:

ue4 package

Both of them fail because of the same issue:

Do you have any guess?

Running tests and packing locally (with the same engine) works fine, this happens only when using containers.

Thanks!

I still need to look into whether those DLL files can be sourced from anywhere other than the mcr.microsoft.com/windows base image, since that image has only existed since Windows Server 2019 / Windows 10 version 1809 and introducing a dependency on it would break compatibility with older versions of Windows. I’ll keep this issue open until a solution has been implemented.
