[RunD8] ERROR: d8 failed.
[RunD8] Task errored in 2.028 seconds

But i can’t find a solution within the error-log why the d8 failed.
The weeks before i had to compile 2-3 times and then it worked. But even that doesn’t help anymore.

I have a farely big program with lots of variables and buttons but i even reduced it to test - but no luck.
I also tried the local export-rename-import

Aja size: 10MB (3MB without assets)

I use these extentions:
SimpleUnzipper2.aix
de.bodymindpower.DownloadToASD.aix
com.puravidaapps.TaifunTools.aix
com.puravidaapps.TaifunTextbox.aix
com.SliderVertical.aix
com.watermelonice.SliderTools.aix
com.vsatish.overlapview.aix

Thanks a lot!

There is a section on d8 errors.

… even reducing to screen1 and removing all blocks didn’t solve the error

Sometimes, after deleting one of the screens, my compilation didn't work. I just had to export the project (aia) and then paste it back in.

That points to the extensions.

(I don't support extensions)

You are using many extensions. Export your AIA then remove one extension try build, do this one by one for each extension. You will find which extension is causing this :+1:

It seens the extention: SimpleUnzipper2.aix was the culprit.
(SimpleUnzipper3.aix also dont’t work)

I tested it before i used it in the main app - worked fine. But in combination with my other extentions and the size of the app it seems to overwhelm the d8.

But it still have to do the buid process up to 3 times before the app compiles.

Thanks for your input!
