### Steps to reproduce

<br>

1. open [https://qa.openproject-edge.com/projects/ACSMT/meetings/4014](https://qa.openproject-edge.com/projects/ACSMT/meetings/4014) and observe that there is an agenda item in the meeting (called **i&#x27;m a big dog yeah call me al capone**)

2. check Participants in the template: [https://qa.openproject-edge.com/projects/ACSMT/meetings/3724](https://qa.openproject-edge.com/projects/ACSMT/meetings/3724)

3. and Participants in the occurrence: [https://qa.openproject-edge.com/projects/ACSMT/meetings/4014](https://qa.openproject-edge.com/projects/ACSMT/meetings/4014)

4. try to move agenda item 2349 to the backlog via the API request (&nbsp;
PATCH 
https://qa.openproject-edge.com/api/v3/meeting\_agenda\_items/2349
body:  {\_links: {section: {href: /api/v3/meeting\_sections/6246}}}
)

5. observe the error: {&quot;\_type&quot;:&quot;Error&quot;,&quot;errorIdentifier&quot;:&quot;urn:openproject-org:api:v3:errors:PropertyConstraintViolation&quot;,&quot;message&quot;:&quot;Presenter is not a valid participant.&quot;,&quot;\_embedded&quot;:{&quot;details&quot;:{&quot;attribute&quot;:&quot;presenter&quot;}}}


Begin of the insertion<br>

The problem is mostly related to permissions because, as you see, a user is a part ofEnd of the insertion the Begin of the insertiontemplate but not a part of occurrence.End of the insertion Begin of the deletion error also appears if we specify presenter in the API like: 
{\_links: {section: {href: /api/v3/meeting\_sections/6246}, presenter: {href: /api/v3/users/558}}}End of the deletion

### What is the buggy behavior?

* It&#x27;s not possible to move agenda item to the backlog via the API call


### What is the expected behavior?

1. It should be possible to achieve this, similar to web
