Zentitle SDK and Library
1140

Invalid feature type for operation

There are four types of features: normal, floating, element pool, and consumption token. Attempting to invoke an operation designed for one type on another type results in an -1140 error, e.g. NSLCheckoutFeature() can only be used to check out a floating feature.

Solution

Check that the operation being attempted is valid for the desired feature type.
