Using seomatic.helper.socialTransform with non PNG or JPG image and no transform name results in error

[kerrig]

Site is using seomatic.helper.socialTransform with an image from a field in the CMS. The image is a webp and the code is not calling a specific transform which is causing the template to throw an error:

The two main issues are because:

• The code is being called without a transform name
• The file is not a PNG or JPG which is the two allowed mime types (ALLOWED_SOCIAL_MIME_TYPES)

This is the code thats calling socialTransform: {% do seomatic.meta.seoImage(seomatic.helper.socialTransform(seoImage)) %}

Here's the code that's failing (in src/helpers/ImageTransform.php):

if (!in_array($mimeType, self::ALLOWED_SOCIAL_MIME_TYPES, false)) {
     $transform->format = self::DEFAULT_SOCIAL_FORMAT;
}

Here's what I did to get it to work:

if (!in_array($mimeType, self::ALLOWED_SOCIAL_MIME_TYPES, false) && $transform !== null) {
     $transform->format = self::DEFAULT_SOCIAL_FORMAT;
}

Once I added the check that transform isn't null, it worked without issue and the SEO Image gets properly set with the webp image.

Versions

• Plugin version: 4.0.38
• Craft version: 4.5.6.1

So at the time, the various social media sites did not allow for webp images, but rather just image/jpeg, image/gif or image/png

It looks like since then, Facebook and Twitter have added support for image/webp so I think he best solution is to add that to the allowed types.
