HI there @Miotx,
This is happening because your column is a text type, and as such the information in your column is a string, and not and array.
A simple solution is to change your mapped value to {{ JSON.parse(item).address1}}
In alternative, you can either:
- Change your column type to JSON so that when you query that column it returns it as an array, rather than a string
- Format it as an array within your query
Hope this helps!
