Photos not Synced

I ran into this problem as well. Quite interestingly, Lightroom is OK to send most of my Albums to Myportfolio and refuses to do it  with a few it doesn't seem to like ... Anyway, after spending way too much time to understand it, I found a quick workaround: instead of trying to send the albums from Lightroom, I can open and import them directly from Myportfolio, it works and at the end of the day I get exactly the same results

I'd been having this same issue, but only occasionally tried to use Portfolio until recently and was getting this same error.  Attempting to share the Album to Portfolio failed with this error, however selecting the pictures within worked just fine.  I just went with this workaround until I got annoyed and dug around more and found this thread.  Being a year old, I'd expected that it would've been fixed so contacted support via chat.

Worked with them a bit, then got bounced over to the Portfolio team, and eventually bounced back to Lightroom support.  Neither really seemed to get the issue I was explaining, and would try to point me to Lightroom Web to do this.  Finally got a support agent this morning named Ankit that was very helpful in troubleshooting the issue.  He also found this thread, and we disabled the "store originals locally" and verified it worked, and re-enabled it and verified it was still broken.  He then was able to find an existing bug report for version 4.  Doesn't really solve the issue, but at least it's a known bug.

So from my experiences, the options/workarounds are:
Select the photos within the Lightroom album, and Right-click share from here

Go to Lightroom Web, click the "..." within the album in the upper right, and click the "send to portfolio"

Uncheck the "store originals locally" - which isn't an acceptable option to me

May 22nd, 2021 and this issue is still not fixed. Doesn't matter if "store a copy of all originals as the specified location" is checked or unchecked.

The images I want to add are in fact uploaded, because they show up when I go to Manage Images > Add Photos > Lightroom on my portfolio site:

It's annoying that I have to leave Lightroom to go and do this. It's not the end of the world, but this is a bug that should be fixed. 

Considering it has been a year, is there an update? I still have the same problem.

This must be a bug because I am also having issues with this. So far none of the describes steps solve the problem for me. 

Setup:

• Adobe Photoshop Lightroom v3.2 20200204-0604-bc5e360
• Windows 10 Pro x64
• Storing photos in cloud as well as external HDD (connected at the time when trying to share to an existing project in Adobe Portfolio)
• All photos are synced to cloud and HDD
• Adding LR photos directly from Portfolio Web UI works (pull). But these photos don't show up in the Portfolio project in LR.
• Pushing photos from LR to Portfolio only seems to work when creating a new project.

I am getting the same issue. However I do not have the box checked to store files. and.. I seem to be able to share ather albums to Portfolio just fine. But One will not and I get the same message you get. I check the cloud icon and it shows that all items are synced and backed up.

I'm glad you figured it out, but that sounds like a bug. It shouldn't work like that.

The error message makes it sound like you are trying to publish from Smart Previews, not originals. That's why I asked if you were using Lightroom Classic. If you don't use Classic, I don't know why you are getting that error message. I'm sorry.

Are you using Lightroom or Lightroom Classic? What exact steps are you taking to share to Adobe Portfolio?
