Unable to pass custom init file #10
Description
I would like to preload some data when starting the server. When I load it through the init file from the default locations e.g. $UserBaseDirectory/Kernel/init.m, it works fine. But when I try to pass a custom init file with the option --initfile, the server does not start and it returns a big error message.

For testing purpose, the content of myinit.m is just test = 123 and to verify if it works, I added ExportForm[{"hello", UnixTime[], test}, "JSON"] in the testapp/index.wl file. I have tried both inside and outside a python virtual environment.
