TYPO3 Core

Yeah, you're right, my snippet doesn't work! :)
Initialy, this snippet was a bit larger and more complicated (the fallback part was some kind of a FLUIDTEMPLATE) so i changed it on the fly without controlling it if is actually working.

But, nevertheless, even with your corrected config it doesn't work either... i still get the error message.

Could it be that ddev (local development env) cause the problem? ATM, i have no possibility to test the project on a real server...

I'm working on a ddev setup myself as well. The problem is that the og:image:type can not be set, before an og:image is set. If the og:image is failing, it will result in the message that it can't handle the og:image:type. Maybe you can try this in another installation?

After I xdebugged the hell out of this, I'm pretty sure that the ordering of the array is completely messed up (see screenshot above), after the 'convertTypoScriptArrayToPlainArray' function call...

Is this even fixable at all? Or can I go around this error by adjusting my config? Does nobody have ever had such a problem?

I don't know how to continue...

in TYPO3 10.4.23 I am using siteconfig (config.yaml) to set the og-image (a few sites in a TYPO3-Install):

Error, i get a correct output for og:image if I remove og:image:width.

(1/1) #1524209729 UnexpectedValueException
This MetaTagManager can't handle property "og:image:width" 

maybe "data" is a problem? again, without og:image:width I get a correct og-image-tag in frontend.

Error:

page {
    meta {
        og:site_name.data = site:theme.brand.name.de
        og:site_name.attribute = property

        og:locale = de_DE
        og:locale.attribute = property

        og:image.data = site:theme.brand.ogimage

        og:image.attribute = property

        og:image:width = 1200
        og:image:width.attribute = property

...

this works (correct image:width in Frontend)

page {
    meta {
        og:site_name.data = site:theme.brand.name.de
        og:site_name.attribute = property

        og:locale = de_DE
        og:locale.attribute = property

        og:image = https://www.example.com/typo3conf/ext/theme/Resources/Public/Images/og_radon.png

        og:image.attribute = property

        og:image:width = 1200
        og:image:width.attribute = property
...

this works too, just removed with comments, but of course no image-width tag in frontend.

page {
    meta {
        og:site_name.data = site:theme.brand.name.de
        og:site_name.attribute = property

        og:locale = de_DE
        og:locale.attribute = property

        og:image.data = site:theme.brand.ogimage

        og:image.attribute = property

        // og:image:width = 1200
        // og:image:width.attribute = property

...

This works without issues in TYPO3 10.4.23

og:image.stdWrap.cObject = TEXT
og:image.stdWrap.cObject {
    if.isFalse.field = og_image
    stdWrap.typolink {
        parameter.stdWrap.cObject = IMG_RESOURCE
        parameter.stdWrap.cObject.file = {$config.social.image}
        returnLast = url
        forceAbsoluteUrl = 1
    }
}

where {$config.social.image} is
