Gallery List has Stopped Functioning - Error with Lookup Column Threshhold

Posted on by SamR

Hello,

I expect my question is more of a lack of knowledge than any sort of technical issue. I have a Gallery that loads on the front page of my app that previously worked without issue. Over the weekend something seems to have changed and now the gallery no longer loads - stating the operation has failed stating "The number of lookup columns it contains exceeds the lookup column threshhold".

I am not sure what happened as I made no changes to my app in the past several days, and am not sure how to go about fixing it. Any advice on what may have happened or what I need to do?

Reference photos below. Thank you very much for any help.

Hi @SamR ,

How many columns of Lookup type do you have in your SharePoint list? Does this article apply?

Hi Warren,

I am honestly not sure - several in this case. Is the count based on the entirety of the the Sharepoint website or the specific list the the gallery is trying to access?

I did make NEW lists over the weekend that have their own lookup columns, but I did not expect any of them to affect previously existing lists/apps.

Hi @SamR ,

It is per list - you might have a read of this blog of mine and reconsider the use of these columns.
