Can’t send a string via REST API into a select field

So, this is my problem. I’ve tried sending a string type into my meta “observacao_intensidade_ataque” but it gives me this error:

{
"code": "rest_invalid_param",
"message": "Parâmetros inválidos: acf",
"data": {
"status": 400,
"params": {
"acf": "acf[observacao_intensidade_ataque] não é um de "
},
"details": {
"acf": {
"code": "rest_invalid_param",
"message": "acf[observacao_intensidade_ataque] não é um de ",
"data": {
"param": "acf[observacao_intensidade_ataque]",
"value": "testing"
}
}
}
}
}

If I send it as array it saves though:

"observacao_intensidade_ataque": {
"value": "1",
"label": "Teste"
},

Problem is, as an array, it does not work correctly although it get’s saved into my database.

I have other fields, all working as expected.

I’ve even checked here and it seems the select type field is supposed to support a “string” type – which obviously makes sense because that’s how it’s saved as a meta anyway.

I’ve tried to find people complaining about same problem but, strangely.

I’m using ACF Pro 6.2.9.

Due to the lack of answers here, I had to find a way to make this happen so I ended up simply adding it to the standard REST like so:

function save_custom_meta_from_rest( $post, $request, $creating ) {
    $params = $request->get_json_params();
    
    if ( isset( $params['observacao_intensidade_ataque'] ) ) {
        update_post_meta( $post->ID, 'observacao_intensidade_ataque', sanitize_text_field( $params['observacao_intensidade_ataque'] ) );
    }

    if ( isset( $params['observacao_incidencia_doenca_parcela'] ) ) {
        update_post_meta( $post->ID, 'observacao_incidencia_doenca_parcela', sanitize_text_field( $params['observacao_incidencia_doenca_parcela'] ) );
    }
}
add_action( 'rest_insert_observacao', 'save_custom_meta_from_rest', 10, 3 );

Hope this helps future people with the same problem.

I just have now to put these two fields outside “acf” and that’s it.
