Error: Debug Failure. False expression: Paths must either both be absolute or both be relative

[Wyatex]

I want to display an image in the notebook, but I got an error when calling await tslab.display.png(xxx).

import * as tslab from "tslab";

// ...

const image = await (await graphQA.getGraphAsync()).drawMermaidPng();

const arrayBuffer = await image.arrayBuffer();
const uint8Array = new Uint8Array(arrayBuffer);

await tslab.display.png(uint8Array);

unexpected error: Error: Debug Failure. False expression: Paths must either both be absolute or both be relative
