Getting intermittent issue with dropdown located with class attribute

[Ananda0488]

await dropDown({class: "location-select"}).select({index:'1'});

When using the above line in my test script, I am getting the below issue intermittently.

Error: DropDown[class*="location-select"] not found

In the web page I am working on, [class="location-select"] locates only one element, but [class*="location-select"] locates 3 elements. Class is the only attribute associated with the element i am trying to locate. Is there any way by which i can avoid this intermittent issue?
