Help: JSON Parse Error with Glide Table Mapping

[Rodney_Trice]

Hi Glide Community,

I’m running into an issue with my app and could really use some guidance. I have a Glide table that’s used to make an API call to retrieve JSON data. That data is parsed into columns using JavaScript, and everything looks fine in the table— all the columns display as expected.

The problem is when I try to use those columns to populate components like lists or cards on a tab or screen. Instead of showing the data, I get this error:

“Error: JSON Parse error: Unexpected identifier ‘undefined’”

You can see from the two screenshots what I’m dealing with:

1. The table showing the parsed column values.
2. The list/card setup and the error message I’m seeing.

Has anyone experienced something similar or know how to fix this? I’m not sure if it’s something in my JavaScript column logic, the API call, or how the component maps the data. Any help would be amazing!

Thanks in advance for your time and support.

Cheers,
RT

Can you show how the collection is configured? Can you also click on the data preview button in the bottom left corner of the layout editor and show what you see there?

I included a few screenshots below for your review. I hope this helps!

Can you show how you’re constructing your JavaScript? Can you use Query JSON instead?
