"Layer is not in the webmap:Service Area" Error?!

[deleted-user-LNABNwA5CZcD]

This is a new one that I cannot seem to find an answer for.

I am trying to upload state senate and house districts to create a searchable map via Information Lookup Web App. I've done this before with no problem. Given the recent elections, I wanted to do new ones with the Carolinas merged (I previously did separate house and senate maps for NC then again for SC; wanted to cut the maps down to two total).

The House of Representatives map and app were no problem and work fine.

The Senate one keeps giving me a bizarre message that doesn't seem to be functional -- just annoying and not something I want confusing people. The message is "Layer is not in the webmap:Service Area" exactly like that (no spaces around colon). I have played with everything I thought I could and tried re-uploading the feature. The weirdest part is that everything with the House version happened in parallel and is fine. What's going on?!

This error can appear if no lookup layer has been configured. Have you set a lookup layer in the application configuration?

Here was the weird thing -- I did this in two Apps in parallel. One either automatically configured the lookup layer or didn't give the error when I was setting it up, then this other one did. Thanks!

I am trying to do this with the configurable app that is downloadable.  But I do not know where in the scripts to set/define the lookup layers.  Do you know where this is located in the downloaded scripts?

Thank you,
