Artifact issue while containerising application on Google cloud build

Hi, I have been facing Julia artifacts error while trying to deploy a Julia application on google cloud build. The application works fine normally and even after dockerizing locally. But for some reason on GCP, it fails with Libiconv_jll artifact missing error.

Error from google cloud build logs:

Container Sandbox: Unsupported syscall UNKNOWN[1008/0x3f0](0x0,0x0,0x0,0x0,0x0,0x0). It is very likely that you can safely ignore this message and that this is not the cause of any error you might be troubleshooting. Please, refer to https://gvisor.dev/docs/user_guide/compatibility/linux/amd64/#UNKNOWN[1008/0x3f0] for more information.
fatal: error thrown and no exception handler available.

So far I have tried following options:

  1. Pkg.instantiate()
  2. adding Manifest.toml so the same dependencies are rebuilt
  3. Supplying Artifacts.toml for Libiconv
  4. Pkg.build() and Pkg.resolve()
    But none seems to be working.
    Any idea how can i resolve the issue? Would appreciate all the suggestions.

This is the artifact (Libiconv) debug information from google cloud build.

The GCP is providing Intel x86 CPU, the application should not have any issue but for some reason running the application still fails.
So the build stage seems to be working but, when I run the application in google cloud run as a service, it fails to start because of the error.
CONFUSED !

@mdsa3d I am running into the same surprising error. Have you found any workaround?

I’m afraid it’s hard to help without more detail. Have you logged into the container and run Pkg.instantiate in there? What happens? Can you try to look around for a Libiconv artifact?

Change Ur package location with a global variable. The install path and running path of the PKG seem different
