Description

I got the following error while quarto preview the qmd file.

Terminating existing preview server....DONE

  /plotly.js (404: Not Found)

May I ask if I missed anything important here?

My quarto=v1.4.550, plotly=v5.19.0, polars=0.20.10

The code is put in this repo, which was running correctly last night on another computer:

It's supposed to look like this:

I believe this is an issue, specific to Windows

• Dashboard is messed up when using plotly on Windows  #8857

You can follow it for a fix.

[cderv]

This will be fixed in next pre-release 1.5, but also backported in our next 1.4 patch release.

I got the same error with jupyter source, on mac

I got the same error with jupyter source, on mac

Unfortunately, this does not help much.
Did you get the same error using the same code as initially shared? Another code?
Under 1.5 pre-release? 1.4.551?

[Zulfikar-TLL]

I get the same error with the same code but in .ipynb . .qmd format works fine.
Set up:

❯ quarto --version
1.5.57
❯ lsb_release -a
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.5 LTS
Release:        22.04
Codename:       jammy
❯ code --version (vscode)
1.94.2

[cderv]

Can you share your ipynb file ? I did quarto convert on the .qmd example here, and then quarto render doc.ipynb --execute and I don't see the issue;

So please, work on a new reproducible example with ipynb, test it with 1.5.57 and latest 1.6 pre-release. If you have issue, open a new one so that we can have a look. Thank you !

[Zulfikar-TLL]

@cderv Thanks for your reply. I also can't reproduce consistently. I will open a new one if I understand further.

I too am getting the same error:

command:
quarto render .\dira\dirb\dirc\dird\plotly_test.ipynb

plotly_test.zip (ipynb file)
localhost-1740655029430.log

If I use embed-resources:true in the header then I get a slightly different ERR_FILE_NOT_FOUND: embed_resources-1740655745824.log
