manifest.files 的 mediaType 不匹配：{}

Error message

manifest.files 的 mediaType 不匹配：{}

What it means

Thrown by validate_manifest_files when a file entry's mediaType does not match the hard-coded expected MIME for its path (e.g. theme.css must be text/css, background.webp must be image/webp). The offending input is the media_type declared for {file.path} in manifest.json; the metadata must agree with the fixed content model of a Dream Skin package.
