I tried to integrate the kirby-builder plugin, but during page creation it gives my this error

`Cannot use a scalar value as an array`

Any advice for this issue?

</div>

Could you please provide more information? Where does the error appear, in the Panel or on the frontend?

Panel: please post blueprint  
Frontend: please post code

Is there a stack trace for the error?

Also, which versions of builder and Kirby?

I used the given example from the builder repo. The error appears in the backend when I try to create a page.

Looks like it’s caused by these two settings:

```auto
columns: 1
max: 10

```

You are right. The page can be created when I remove those lines.  
Thank you for your help 🙂

It’s not really a solution but a workaround. Not sure if that’s a bug in the plugin or somewhere else.

I’m opening an issue for the builder. Maybe the author knows what has happened.

I just saw an error like this yesterday when editing blueprints. I found my error.  
But, perhaps a more descriptive error message would help.
