Known Issues

Issue Description
Cannot disable retry delay for a Qualification type once enabled. There is currently no way to disable the ability to re-request a Qualification if the Qualification type allows retries. This release introduces the ability to add a retry delay to a type that doesn't have one, or modify the delay if it does. Once a type has a retry delay, then retries are permanently enabled for the type.
Cannot remove a test from a Qualification type. There is currently no way to remove a Qualification test from a Qualification type that has one. This release introduces the ability to configure a Qualification type to automatically approve Qualification requests instead of using a Qualification test. Because tests cannot be removed from an existing type, a Qualification type with a test cannot be re-configured to use the auto-approval feature.
SearchHITs can include duplicate HITs in results. The SearchHITs API may return a HIT more than once in the results if there are more than 100 active HITs created by the caller.
Incorrect number returned for TotalNumResults response element of GetReviewableHITs. GetReviewableHITs does not reliably return the correct number for the TotalNumResults response element.
