importKey RSA-OAEP with SHA-1 not working on safari 11

Hey , I try to use 'importkey' on safari 11 and also on outlook for mac and both I get error.
` window.crypto.subtle.importKey(
"jwk",
{
"kty": "RSA",
"e": difensoPublicKeyE,
"n": difensoPublicKeyN,
"alg": "RSA-OAEP",
"ext": true
},
{ /
name: "RSA-OAEP",
hash: { name: "SHA-1" },
},
true,
["encrypt"]
).then(function (publicKey) {`

Then I get this error:
**OpeartionTypeError: Member JsonWebKey.kty is required and must be an instance of DOMString**

Not matter what I try it's same error... maybe someone can help please?

Thx
