Running the contributed command: 'language-julia.executeCellAndMove' failed

On my RHEL7 Visual Studio Code, I can not run my Hello World program from the built-in REPL. There is something wrong with the installation but I can not figure out what it is. The error I see is

Running the contributed command: 'language-julia.executeCellAndMove' failed.

I am running Visual Studio Code 1.56.2 and Julia Language Support 1.2.8.

The program is not the issue, it works on the terminal and on a VSC under Windows:

#!/usr/bin/env julia

module Test
    function test()
        println("Hello world!")
    end
end

Test.test()

Reinstalling the Julia extension gives this error:
Could not start the Julia language server. Make sure the configuration setting julia.executablePath points to the Julia binary.

… but this is also not the issue, I have julia in the PATH environment variable and I have added it in the field “Julia: Executable Path … Points to the julia executable.”

Any ideas?
