Invalid file type: image when uploading og:image

[swwwwwwww-www]

Hey,

uploading a preview image throws an error. Both on page.yml and site.yml

Best,
Stefan

Hi @swwwwwwww-www! I'm Dosu and I’m helping the kirby-seo team.

The kirby-seo plugin's og:image field is set up to accept standard image uploads (like PNG and JPG) and does not restrict file types by default. If you're seeing an "Invalid file type: image" error, it's most likely caused by a custom restriction in your Kirby config or a blueprint elsewhere in your project—such as a file template restriction set via the tobimori.seo.files.template option or a misconfiguration in your Kirby setup. The plugin itself expects the normal Kirby image upload flow, so unless you've customized these settings, PNGs should work fine. Double-check your config and any custom file templates or blueprint restrictions that might be interfering with uploads.

@dosu

The reference file blueprints/fields/og-image.php looks the same on my side. Nothing specific has been set up but the 'tobimori.seo.canonicalBase' entry within the config file.

The kirby-seo plugin doesn't restrict file types for og:image uploads and doesn't generate the "Invalid file type: image" error—this comes from Kirby core or another plugin. Since your config and blueprint match the defaults and you haven't set any restrictive options, check for custom file blueprints in site/blueprints/files/*.yml, global file restrictions in config.php, or other plugins that might affect uploads. Disabling other plugins temporarily can help isolate the cause. The 'tobimori.seo.canonicalBase' setting is unrelated to file uploads. More details on the plugin's blueprint logic are here: og-image.php.

Does it happen with different images?

[swwwwwwww-www]

Yes, tried a few … jpg, png … all the same error.

[tobimori]

Are you on Kirby 5?

[swwwwwwww-www]

Yes. 5.0.0-beta.6 to be precise :)

[tobimori]

Have you tried updating to 5.1.1?

[swwwwwwww-www]

I just updated it … the error remains.
