What browsers do you use to access the UI ?

Microsoft Edge

This parseInt() leads to the problem:

ComfyUI_frontend/src/scripts/app.ts

Line 2806 in 720e7e1

const node = app.graph.getNodeById(Number.parseInt(id))

Looks like graph uses Number as its id type? If so, it may be hard to directly fix this problem. But I think adding a preprocess step to map string ids to integer ids will work at least.
