Py scripts not loading at OH startup

[wawa79]

Bug description I followed the installation procedure and got it barely working except that py scripts (typically the hello_world.py script) are not loaded/executed by OH until I make a change and save the file.

Expected behavior Scripts should load on OH startup to ensure correct recovery after failure of OH system.

Logs On OH startup:

And nothing else until I make a change in the py file. Then, after the file is modified and saved:

This was an issue in OHC that has been fixed for the OH 3.0 release. I've made a jar with the fix for OH 2.5.x...

Great, thank you! But it might be helpful to reference your in the doc as I did not find it by myself.

[5iver]

Good idea... I'll add it to the first page of the docs with the other version specific info.
