Hey @frankl7800! This should've been fixed with #1060 - released with @frctl/handlebars v1.2.11 and @frctl/fractal v1.5.9. Can you maybe investigate a bit further, where the old handlebars adapter is coming from? Or try updating it to the latest manually with npm update @frctl/handlebars?

[frankl7800]

My handlebars adapter is version 1.2.13 and comming from yarn: https://yarnpkg.com/package/@frctl/handlebars

yarn list --pattern "frctl"

yarn list v1.22.15
├─ @frctl/core@0.3.3
├─ @frctl/fractal@1.5.11
│  └─ @frctl/mandelbrot@1.9.4
├─ @frctl/handlebars@1.2.13
├─ @frctl/mandelbrot@1.7.0
└─ @frctl/web@0.1.10

If I look at my own current project where I also have 1.2.13 installed, inspect the actually installed package, it seems to be fine:

The code in this repo is also correct for the handlebars adapter. I'll close the issue, but feel free to ping me if you find out something new (e.g. we've been looking at the wrong package or whatever)
