I'm trying to programmatically add a custom option to a product, there are no errors being returned, but the custom option doesn't get added. I've tried a few methods to achieve this, without much luck.

Here's my code as it stands:

$product = $this->objectManager->get('Magento\Catalog\Model\Product')->load($productID);

$productOption = $this->objectManager->get('Magento\Catalog\Model\Product\Option');
$productOption->setProduct($product);
$productOption->setTitle('Text');
$productOption->setType('area');
$productOption->setIsRequire(1);
$productOption->setValues([
    'title' => 'Text',
    'price' => '1.00',
    'max_characters' => '50',
    'price_type' => 'fixed',
    'sort_order' => '1'
]);
$product->addOption($productOption);
$product->save();

Any ideas what I'm doing wrong?

UPDATE

I've now tried a different method:

$product = $this->objectManager->get('Magento\Catalog\Model\Product')->load($productID);
$product->unsetOptions();
$product->setHasOptions(1);
$product->setCanSaveCustomOptions(true);
$product->getOptionInstance()->addOption([
    'title' => 'Text',
    'type' => 'area',
    'is_require' => 1,
    'values' => [
        [
            'title' => 'Text',
            'price' => '1.00',
            'price_type' => 'fixed',
            'max_characters' => '50'
        ]
    ]
]);

But this gives me the following error:

[Magento\Framework\Validator\Exception] Invalid option value

However, I cannot figure out what's invalid.

You don't need to specify values for the option type you are trying to add. Please try example below.

/** @var \Magento\Catalog\Api\Data\ProductCustomOptionInterface $customOption */
$customOption = $this->objectManager->create('Magento\Catalog\Api\Data\ProductCustomOptionInterface');
$customOption->setTitle('Text')
    ->setType('area')
    ->setIsRequire(true)
    ->setSortOrder(1)
    ->setPrice(1.00)
    ->setPriceType('fixed')
    ->setMaxCharacters(50)
    ->setProductSku($product->getSku());
$customOptions[] = $customOption;
$product->setOptions($customOptions)->save();

Also, you can find a lot of examples on how to add products, attributes, options, etc in fixtures for integration tests. For instance, take a look in dev/tests/integration/testsuite/Magento/Catalog/_files
