Error message: ?:0: attempt to compare nil with string

I get this message when trying to add an image to Quick Collection in the latest LR Classic update:

?:0: attempt to compare nil with string

How to solve this? Thank you

Very pleased to see the workaround here. T hank you.

Less pleased that such a significant, irritating bug got through Adobe's testing.

Even less pleased that it's been five weeks and Adobe has not released a patched version.  This seems the kind of major, simple bug that would warrant an emergency release rather than waiting for a future version.

Thanks Jhon! Hoping this works. I been dealing with this inconvinient situation for a good 2 months. An update has yet to fix this issue.

"I been dealing with this inconvinient situation for a good 2 months. An update has yet to fix this issue."

The bug was introduced in LR 10.0.  LR 10.1 will likely be released later in December and will very possibly fix the bug.

This bug has been fixed in LrC 10.1

Evidently it has not, as I found this thread when the issue happened to me
last night, and I’m running 10.1.

[mremijan]

I have 10.1 now and I've confirmed that it's fixed for me.

[gorongosaw64728959]

Not fixed, I still have the same error. EXTREMELY annoying.

Do you have the plugin LogiOptions? known pos.

"Evidently it has not, as I found this thread when the issue happened to me last night, and I’m running 10.1."

Double-check you're really running 10.1 by doing the menu command Help > System Info. The Creative Cloud app sometimes fools people into thinking they're running on the "latest".

What were you doing in LR when the message appeared?  What version is shown when you do the menu command Help > System Info?
