We want to update a multiple-choice custom-field for a product, but we get following error:
The operation failed with an error. 422: Expected ‘number’ as option ID for multi options custom field, instead “NaN” was passed (Please check developers.pipedrive.com for more information about Pipedrive API.)
We are sending the ID´s of the options for multiple-choice as comma-separated values e.g.: 15,182
What are we doing wrong?
