nextToken

The nextToken value returned from a previous paginated DescribeRepositories request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return. This option cannot be used when you specify repositories with repositoryNames.

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
