In the K2 Management site, when navigating to any SmartObjects under "Categories" or to the Odata and Workflow Rest API wizard, the following error appears:
Procedure that resulted in this scenario:
1. K2 APIs (SmartObject Odata and Workflow REST) was enabled
2. This will write some entries relating to this configuration in the default environment library selected (Environment Library A)
3. Default Environment Library was changed to Environment Library B.
* In typical installations, two environment libraries with default name "Development" and "Production" will be created; both containing the same server values
4. Environment Library B does not have these Odata/Workflow REST settings (as it is only written to the default environment library A at the time of API activation)
5. Navigating to any SmartObjects under "Categories" or the the APIs configuration wizard errors as it is attempting to load empty environment fields.
Possible solutions include:
1. Copy ALL missing environment field values relating to SmartObject Odata and Workflow REST from the initial environment library to the current default environment library; perform an IISRESET for immediate effect as environment fields are cached.
The Field Description is also a required field.
2. Alternatively, setting the default environment library first before enabling the APIs during the installation process will also prevent this scenario.
