Api Call on Meetings with filter returns duplicate entries by contacts

[hiesscher]

Issue

If a meeting with several contacts as participants is accessed via the API using a filter, several entities are output. All entities contain the same Contact.

Possible Fix

When querying using ID, without filter, the error does not appear.
[...]/legacy/Api/V8/module/Meeting/32fbac34-7d90-00e3-17d8-678a08d912a4

Steps to Reproduce the Issue

1. Create a meeting with multiple contacts as participants
2. Query the meeting via the API using filters, e.g.
[...]/legacy/Api/V8/module/Meeting?filter[id][eq]=32fbac34-7d90-00e3-17d8-678a08d912a4
