Scripting not working on runtime

[nikkieke]

Submission checklist

• I have confirmed the issue is present in the latest version of @rive-app/react-canvas or @rive-app/react-webgl2 (or the renderer variant I'm using)
• I have searched the documentation and forums and could not find an answer
• I have searched existing issues and this is not a duplicate

Description

I am loading a .riv file whose rendering and animation is entirely handled by a Luau script and it results in a blank artboard. The script does not appear to execute on runtime. It works as expected in the rive editor.

The following appear in the browser console:

[activate] script "Globe" generatorFunctionRef=13 -> lua ref=13
[verifyImpl] entering verify for object protocol=1, stack top type=7

Environment:
Package: @rive-app/react-webgl2 (latest version)
Framework: Next.js 15 / React 19
Browser: Chrome (latest)

Expected: The Luau script named "Globe" executes and renders the animation.
Actual: Artboard is blank. The [activate] log suggests the runtime is attempting to initialize the script.

Hi @nikkieke - would you mind sharing a short repro project (can add a .zip) showing that the riv is not rendering? This would be super helpful for us to investigate 🙏

We are aware we accidentally introduced some error logging with those messages you indicated, but those particular logs should not be indicative of a core underlying error. They will be removed in the next patch release.

In the meantime, can you try with v4.28.3 of the runtime?

Hi @zplata
I have tried using v4.28.3 of the runtime, but I still experience the same issue.
I have attached a .zip of the short repro project here.

Thank you!

Perfect, I'm able to repro this, thank you! @nikkieke One last thing I forgot to ask - if you have it, could you also send over the .rev as well so we can inspect in the editor?

Also - in the package.json, if you change the dependency version from "^4.28.3" to 4.28.3 and lock it down that, way and run a new npm i, that previous version should render the graphic as expected.

EDIT: I did notice one thing - try setting autoBind: true on the latest version of the runtime, this may fix the graphic. Digging into this.

I pinned the version and it works fine - thank you!
I don't have the .rev file right now, but will share once I get a hold of it.

[nikkieke]

yes, setting autobind: true on the latest version works as well. the animation renders as expected.

[zplata]

Thanks for confirming - the .rev will still be super helpful for us to dig in from editor side. Thanks in advance!

[zplata]

This should be fixed in v2.48.5 if you want to try bumping to that @nikkieke

[nikkieke]

it works as well.. thank you! @zplata

EDIT: it doesn't work unless autobind is set to true.
