/api/applications returns empty result list, but "totalCount" says that there should be items

[SebastianKotstein]

• [X] The issue is present in the latest release.
• [X] I have searched the issues of this repository and believe that this is not a duplicate.

What happened?

When trying to fetch the list of applications via the HTTP API of the application server, the result list is empty, but the "totalCount" property (as well as the web interface of the application server) indicates that there must be, in my setup, 10 applications.

What did you expect?

A JSON object for each application contained in "result"

Steps to reproduce this issue

Steps:

1. curl -X GET --header 'Accept: application/json' --header 'Grpc-Metadata-Authorization: Bearer 'http://MY_IP/api/applications'
2. Response is: { "totalCount": "10", "result": [] }

Could you share your log output?

It looks like you didn't specify the limit argument in your request, in which case you do get the total count, but not the result-set.

Many thanks for your quick reply! So it is not an issue as supposed, but a feature. I have tested it again and now it works!
