Pixieset plugin publish error

I'm getting an intermittent error message when I see the Pixieset plugin in Lightroom. The problem went away a few weeks ago but has now returned. Now I can't publish anything. The specific error message is as follows:

Can't update this collection
An internal error has occurred: src/pixieset.lrdevplugin/PixiesetAPI.lua:106: attempt to index local 'response' (a nil value)

Any ideas please?

Thanks very much!

There are a couple other recent reports of internal errors with the Pixieset plugin:

The error message indicates a programming error either in the Pixieset plugin or in LR. The file path in the error message, "src/pixieset.Irdevplugin/PixiesetAPI.lua", suggests you may have an older or beta version of the plugin installed.

So remove the current plugin and download and reinstall the current version:

If that doesn't help, you'll need to contact Pixieset.
Thanks both. Here's Pixieset's response:

The error you’re encountering seems to be related to Lightroom’s most recent version updates (v13 and v13.1), and our Tech Team is currently looking into this further. We’ll provide more information as soon as we can! In the meantime, to help ensure you’re able to upload to your collections via the Lightroom Plugin successfully, the best solution would be to revert back to v12 of Lightroom. Adobe has more information on how to do this here.
I encountered the same problem using Lightroom version 13.0.1. I reverted back to version 13 and the problem was fixed.
So the plug-in is working with v13.0? I'm on 13.0.1. Looks like the Lr plug in hasn't been updated for quite a while...
Well I rolled back to v13.0 but I now get an error message telling that my files are too large! Hmmm.

Pixieset recommends that I upgrade my OS to Sonoma. I'm on Monterey now.

Does Lr work well on Sonoma please?
