How to create a Fieldtype as multichoice and set the values?

[alfredoquintana]

Hi i am trying to create a multichoice metadata type and set the values. i have tried to use the FieldCreationInformation.

$metadataName = 'new metadata'; $library = $this->credentials->getWeb()->getLists()->getByTitle($dir); $array[] = ['value1', 'value2', 'value3'];

`       $fieldCreationInformation = new FieldCreationInformation();
        $fieldCreationInformation->Title = $metadataName;
        $fieldCreationInformation->Choices = $array;
        $fieldCreationInformation->FieldTypeKind = FieldType::MultiChoice;
        $metadataField = $library->getFields()->add($fieldCreationInformation);`

and have this error

{"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-EN","value":" Property 'Choices' does not exist on type 'SP.Field'. Make sure you only use property names that are defined by the type."}}}

thank you very much, have a nice day!
