Possible Issue with Automattic's Export to Lightroom plugin

[khurtwilliams]

For several years, I have used Automattic's Lightroom plugin to export images directly to my Jetpack-powered WordPress website as part of my photo blogging workflow. Something went wrong last week.

I updated Jetpack to version 9.5 and WordPress to version 5.7 right before I started getting a Lightroom UI error. I removed and re-installed JetPack multiple times.

I worked with JetPack support to troubleshoot the issue, and we found this in my Apache error logs right after each attempt to use the Lightroom WordPress export plugin.

There was an update to Post Kinds that I had applied before I updated JetPack 9.5 and WordPress 5.7. When I disable Post Kinds, the export from Lightroom to WordPress works, and I don't see the error.
