I traced down this error. In this case, ng-repeat is not using a particular field as the key for looping because the data from the server is in a complex data structure, an array of objects. In the error message, it refers to "string: e” as the key where ‘e’ is just one of the characters in the whole data string. We will need to add the "track by", suggested in the angular error message, and use $index added by ng-repeat.
