White Thumbnail Problem

Thumbnail is not generated for this notebook

Sadly, In the collection, the thumbnail is not generated only for this particular notebook

I think the issue is related to the notebook running time (it’s about 10 seconds before result)

Hi David,

Yep - it’s the running time. Thumbnails are currently generated on a headless chrome instance with an execution limit of 30s. Given that this takes about 10s on my fancy MacBook, it’s likely taking a bit over 30s on the relatively smaller server instance.

One more problem I observed is call stack count limitations

It works on the laptop, but as it looks like, maximum call stack error is fired when headless chrome visits it

Seems pretty weak server
