Copy & Pasting is not working in self-hosted composition

friedbun · September 2, 2025, 7:30am

I’m using Penpot with the suggested docker composition hosted on a personal NAS device.

I’ve come to notice that copy & paste for objects on my page appears to not work?

Repro scenario:

Create a new page
Create a board
Add objects to board
right-click board
click cut
click paste

The following appears in the webconsole (firefox):

Clipboard error: TypeError: can't access property "readText", a is undefined\

Stacktrace:

AFAICT this is also happening in Chrome:
Exception in the console:

I have the same problem in version 2.10, running in Microsoft Edge
