Hello World Sample Application not Building


I’ve just got an X4 gateway. This is not my first Digi product, but the first one I’ve used Digi ESP for Python with.

The problem I have is that I cannot build the hello world application. The building process gets to about 20% (“Translating Project Paths…”) and then stays there for a little while after which fails with an error:

Errors occurred during the build. Errors running builder ‘Digi Python Application Builder’ on project ‘hello_world’. String index out of range: -1

Has anyone ever seen this? I am pretty sure that I was able to compile this project a couple of time yesterday and then suddenly it stopped working.

I’ve already re-installed the ESP, but with no change.

The only thing that’s changed on my PC is that I installed an MQTT server application, but I don’t think that it is auto-starting anyway.

Any idea why this may be happening?

I moved your thread to the python forum since you’re having issues building a python script fyi.
