* s3vectors: bound ListVectors maxResults and segment parameters segmentCount had no upper bound, so segmentCount=1000000, segmentIndex=999999 made the segment emulation scan the whole index to return nothing. Apply the AWS ListVectors windows before authorization and any engine call: maxResults 1..1000, segmentCount 1..16, segmentIndex in [0, segmentCount), and segmentCount and segmentIndex given together. The fields become pointers so an explicit 0 is rejected while an omitted one still takes the default.

AWS returns the lowercase enum values. Lowercase the metric when the index is created, and again when the record is read so indexes already stored in mixed case render the same.
