AIO 1.31.0 Not Saving Group Fields via API

Hello Cameron,

Can you share the group field settings and sub-fields that you try to update the value via POST API? I try with simple group field

'fields'   => [
    [
        'name'              => __( 'Group', 'your-text-domain' ),
        'id'                => $prefix . 'group_ubce2rqmfm',
        'type'              => 'group',
        'fields'            => [
            [
                'name'              => __( 'Text', 'your-text-domain' ),
                'id'                => $prefix . 'text_wulikp8w5km',
                'type'              => 'text',
            ],
        ],
    ],
],

and I can update the subfield text value with POST API properly when using the latest version MB AIO 1.31.0.
Also, do you use any caching plugins on your site or on your hosting? Please disable them all and recheck this issue.

Hello,

Thanks for the details. I also see the data is not inserted into the custom table. There could be an issue with the Rest API and custom table in the new version. I will inform the development team to check and fix it soon.

Dear Cameron,

I have checked MB Rest API and found no issues, please make sure you have set 'clone' => true to **HighlightsGroup** field. Here is the meta box that have similar structure with yours.

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'Test',
        'fields' => [
            [
                'name' => 'HighlightsGroup',
                'id'   => 'HighlightsGroup',
                'type' => 'group',
                'clone' => true,
                'fields' => [
                    [
                       'name' => 'highlight',
                       'id'   => 'highlight',
                       'type' => 'text',
                    ],
                ]
            ],
        ],
    ];
    return $meta_boxes;
} );

Since your **HighlightsGroup** field expects an array, you have to set clone => true.

Otherwise, if you don't want cloneable group, here is the correct json format:

{
    "meta_box": {
        "HighlightsGroup": {
            "highlight": "This is another test"
        }
    }
}

Cheers!
