Wordpress-seo: Getting an error after updating to Yoast SEO 7.4: Warning: Illegal string offset 'url'

[Jerparx]

Please give us a description of what happened.

After updating to Yoast SEO/Premium 7.4, a warning message is showing on customer's site:
Warning: Illegal string offset 'url'in /home/*/public_html/wp-content/plugins/wordpress-seo-premium/frontend/class-opengraph-image.php on line 151*

$image_url = trim( apply_filters( 'wpseo_opengraph_image', $attachment['url'] ) );

This message seems to be showing on pages where an image is uploaded but I could not reproduce the issue yet.

The same issue is reported in forums: https://wordpress.org/support/topic/version-7-4-breaks-site/

Please describe what you expected to happen and why.

No error/warning message showing.

How can we reproduce this behavior?

Unable to reproduce yet but customers reporting the issue said that the warning message is showing on pages with images.

Reverting to 7.3 fixed a customer's issue.

Technical info

• WordPress version: 4.9.5
• Yoast SEO version: 7.4
• Relevant plugins in case of a bug: still investigating.

Per your request, uploaded code for page displaying this issue. It affects every page as far as I can see, so I'm just uploading the home page source code.
