Warning: Undefined array key “uniqueId”

Hi @dgomez,

We don’t have a Row Layout Block.

What we have is a GB Grid Block. Reference: https://docs.generateblocks.com/article/grid-overview/

The Row Block is from WordPress. It would be best to reach out in the WordPress forum regarding this instead: https://www.ads-software.com/support/forum/wp-advanced/

I would also suggest disabling plugins to test for any plugin-conflict that may cause this issue.

The error indicates that the problem is with a file that is part of generate blocks though.

I redid the formating on the page and the error is gone. Maybe something got corrupted.

I see. Glad you found a solution. Perhaps indeed it was corrupted.

I have the same error, same line 1004 – clearly it’s not a random error.

Hi there,

each of the GB blocks is given a uniqueID when added to a page. That error would suggest that a Container Block on your page is missing its uniqueID – which should not happen.

You may need to rebuild that page layout to fix that problem.

I solved it. I just deleted the block containing the paragraph and placed it back in. Thank you!

Glad to hear that

I’m having the same issue — the site is quite large, though with hundreds of pages so rebuilding every one to find the problem is not practical.

Is there any way to isolate it?

Hi there,

Unfortunately, there’s no easy way to isolate it.

You can start a staging site, and enable displaying PHP errors on the Frontend with a config line like this:

define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', true);

Then, try to view pages from when you recalled the error started appearing.
