How to reproduce¶

TS-setup:

lib.teaserMediaReference = FILES
lib.teaserMediaReference {
    references {
        data = levelmedia:-1, slide
        treatIdAsReference = 1
    }

    begin = 0
    maxItems = 1

    renderObj = IMG_RESOURCE
    renderObj.file {
        import.data = file:current:uid
        treatIdAsReference = 1

        width = 751m
        height = 752m
        minWidth = 200
        minHeight =  200
    }
}

page.meta {
    og:image.stdWrap.cObject < lib.teaserMediaReference
    og:image.stdWrap.wrap = {$protocol}://{$siteurl}/|
    og:image.attribute = property
    og:image:width.stdWrap.data = TSFE:lastImgResourceInfo|0
    og:image:width.attribute = property
    og:image:height.stdWrap.data = TSFE:lastImgResourceInfo|1
    og:image:height.attribute = property

Probable fix¶

TYPO3 9: https://api.typo3.org/9.5/frontend_2_classes_2_http_2_request_handler_8php_source.html#l01039
TYPO3 10: https://api.typo3.org/master/frontend_2_classes_2_http_2_request_handler_8php_source.html#l00930

Change

                $nodeValue = $properties['_typoScriptNodeValue'] ?? '';
                $value = trim($cObj->stdWrap($nodeValue, $metaTagTypoScript[$key . '.']) ?? '');
                if ($value === '' && !empty($properties['value'])) {
                    $value = $properties['value'];
                    $replace = false;
                }

to

                $nodeValue = $properties['_typoScriptNodeValue'] ?? '';
                $nodeValueStdWrapped = $cObj->stdWrap($nodeValue, $metaTagTypoScript[$key . '.']);
                $value = is_string($nodeValueStdWrapped) ? trim($nodeValueStdWrapped) : '';
                if ($value === '' && !empty($properties['value'])) {
                    $value = $properties['value'];
                    $replace = false;
                }

Maybe the underlying problem actually is that the values of width and height get typecastet to integer instead of string and the error is found in a totally different place.

See TS-setup:

lib.teaserMediaReference = FILES
lib.teaserMediaReference {
    [...]
    renderObj = IMG_RESOURCE
    renderObj.file {
        [...]
        width = 751m
        height = 752m
        [...]
    }
}

page.meta {
    og:image.stdWrap.cObject < lib.teaserMediaReference
    og:image.stdWrap.wrap = {$protocol}://{$siteurl}/|
    og:image.attribute = property
    [...]
}
