Syncing from desktop to cloud

Hi there,

Thanks for reaching out. We're sorry for the trouble with Lightroom. We're here to help.

Could you please share the version of Lightroom & the operating system you are working on? Has this started to happen recently? Have you newly imported a large batch of images in Lightroom? What format of photos do you work with, JPEG or RAW? Have you tried signing out of Lightroom & the Creative Cloud & sign in again?

Please try this;

• Press the Alt key (Win) or Option key (Mac), and click the cloud icon in Lightroom > Click on View.
• Check the images pending sync & apply flags/ratings to these images.

You can also log on to Lightroom Web (https://lightroom.adobe.com) to check current Sync issues on the left part of the screen.

If there are any sync issues, click on them to know more, find the original for those images, and back them up safely before you empty the Sync issues from Lightroom Web. As long as there are sync issues on the Web, you can encounter trouble in syncing images & edits.

Here is a similar community discussion. Please check the suggestion here: https://community.adobe.com/t5/lightroom-ecosystem-cloud-based-bugs/p-error-in-cloud-sync-dialog-quot-some-photos-invalid-quot/idi-p/12235796

Let us know how it goes.
Thanks!
