Location Autocomplete api call failing with 401 Unauthorized error

In order to search for projects by location, users select a Country and type into the address bar, which calls the HERE api that autocompletes searches for addresses/landmarks. However, these calls are now returning error 401 (Unauthorized), which indicates we need to update our credentials and/or switch to a newer api.
