/// App to Update or remove Metadata fields of a Multimedia Component.

/// with a Category field referencing a non-existing keyword. This caused
/// publishing issues with DXA, as it attempts to render the fields of the
/// Component and fails.

/// Thanks for the help from the following StackOverflow post:
