SuiteCRM 8.3 API - Filter Meeting results using Attributes

I’m trying to do filters based on the documentation. I keep getting “Filter field status must be an array”.
Is there something that I’m doing wrong ?

curl --globoff -X GET -H "Content-Type: application/json" -H "Authorization: Bearer secret" \
https://https://internal.domain.com:8443/legacy/Api/V8/module/Meetings?filter[status]=[[eq]]Planned

{
    "errors": {
        "status": 400,
        "title": null,
        "detail": "Filter field status must be an array"
    }

Another question. I also added a custom field in the attributes. Can I filter results using custom fields ?

Thanks.

I found that this filter format works.
