Slim normalizes headers when creating them from the environment but preserves the capitalized HTTP_ prefixed values from the
$_SERVERarray as original keys¹.$headers->all()then uses the original keys which makes the Guzzle client use them as actual header names.So we need to remove the original keys by setting all values again with their normalized keys.
