Dear community,

I tried to do the base tutorial for showing the Panda robot. But I get a black screen on the browser with the error: "Application error: a client-side exception has occurred (see the browser console for more information)."

On the browser console i get the following errors:

I have tried with Python 3.8 and 3.9 and with the browsers: Firefox and Chrome on Windows 11. But same error appears.

How can I solve?

I think it related to the issue of Swift, similar with:
#4

but I tried to using
from roboticstoolbox.backends.swift import Swift
and also tried to add
os.chdir(root_dir.anchor) in SwiftRoute.py and even switch back to Python 3.6

but unfortunately nothing works.
Hopefully it will be fixed soon.

Same here when trying to record a video. Without recording it works great. Browser: Firefox, OS: Ubuntu 20

@oldgunlu I have the same problem. Have you found any other viable alternatives?

[kappa95]

The pull request #52 solved the issue for me. Temporary solution: make that changes on your path.

[oldgunlu]

@kappa95 Problem solved, Thanks a lot !
@ningtianze you can try to make change, it works for me in windows： #52

[kongyuanchao]

same issues happened on Windows

[kanyunke]

On windows, same problem, pull request #52 solved for me too.
