Hello,

I'm trying to fetch workpackages with specific Versions via the API/V3.

The request is:

https://<servername>/api/v3/work_packages?filters=%5B%7B%22version%22%3A%7B%22operator%22%3A%22=%22%2C%22values%22%3A%5B%221%22%5D%7D%7D%5D

or 

https://<servername>/api/v3/work_packages?filters=[{"version":{"operator":"=","values":["1"]}}]

It is always returned with status 400:

{
   "_type": "Error",
   "errorIdentifier": "urn:openproject-org:api:v3:errors:InvalidQuery",
   "message": "Version filter has invalid values."
}

How do I provide the correct filter values?

Thanks
