ERROR: cannot init Sys.homeDir running a Fantom app based on afBedSheet on Mac OS X

Question

Following the instructions from Alien Factory's afBedNap to build a web app using the afBedSheet framework for Fantom I got this error at the end of step 3 (running the app):

$ fan myAfBedNap

The path /Users/coder/apps/fantom-1.0.66 exists and is where I installed Fantom. I ran export FAN_HOME="/Users/coder/apps/fantom-1.0.66" but this made no difference.

If I run $FAN_HOME/bin/fan -version this is what I get:

I can't find a solution in Fantom forums. Any ideas, please?

Answer 1

It looks like the app is falling over when it launches the BedSheet Development Proxy so try starting the web app with out it.

In /myAfBedNap/fan/Main.fan remove the -proxy option so it looks like:

class Main {
    Int main() {
        afBedSheet::Main().main("-env dev myAfBedNap 8069".split)
    }
}
