We have just detected that queryParam apiUuid is not working in /api-management/1.0/applications after upgraded to Portal 5.3.2.
For instance, invoking GET /api-management/1.0/applications?apiUuid=<uuid >
will return all the existing applications ), regardless the apiUuid value passed.
Portal 5.3.2
This is a know issue and will be resolved in portal 5.3.3 .
