Symbols not appearing on canvas when editing, but layers are present

Builder content link

Builder public api key
8edea6d82d464d9ea98caef0adf910cd

What are you trying to accomplish
When I create a symbol and then try and edit it, only the layers show up in the visual editor - there is nothing on the canvas. I can edit a text layer and save, but the changes do not propagate to the instances.

Hi, welcome to the Builder Forum!
Thank you for submitting your question - My name is Veronika Pilipenko and I am a Customer Engineer here at Builder.

Could you please share the code where your symbol preview is registered?

Usually an issue like this indicates that you’re using the incorrect API key, or your registered model name is incorrect in the Builder component. You can find out more in our docs here.

Let us know if that helps or if you have any other questions,

Thank you!
