jsonWebtoken nodeJs wielding different results compared to https://jwt.io/

Question

I'm trying to get a jsonWebtoken with jwt.sign(payload, secretOrPrivateKey, [options, callback]) but I just can't reproduce the same value which is created online on: https://jwt.io/#debugger-io

HeaderPart: { "alg": "HS256" }

PayloadPart: { "sub": "0ed971b7ee04e9aeab20b00a0edbbd9d06f4bf4bfb7cee96fa3066a2c65eb319" }

SecretKey: "458ee9b7330d3e05faf6e60d3fa3a684e110668263bd0db285863a380de21c41"

Using https://jwt.io/#debugger-io I get the following token which matches the one from the documentation I saw:

eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJSNGpONjRUSU5tUzJZeTBOYW1IamFFSDZQcTB1MjFlQ09WWHNhTTFxMEgyMEdIMm1oQlA0WG1Gd1hVbGNuWHl2In0.QaPYHUiSKmQp1yVBiOSGtRxukEKVMrVy0a9Y_9qZSoc

Using jwt.sign:

const bearerToken = jwt.sign(
{
    sub: '0ed971b7ee04e9aeab20b00a0edbbd9d06f4bf4bfb7cee96fa3066a2c65eb319'
},
'458ee9b7330d3e05faf6e60d3fa3a684e110668263bd0db285863a380de21c41');

Value = eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJSNGpONjRUSU5tUzJZeTBOYW1IamFFSDZQcTB1MjFlQ09WWHNhTTFxMEgyMEdIMm1oQlA0WG1Gd1hVbGNuWHl2IiwiaWF0IjoxNjUxODMyOTE5fQ._FOsHb-RKP8kXpYOaJpoY8x4ijAFXnRBq67oQeflpyE

Since jwt automatically adds {typ: "JWT"} to the header if the payload is an object it makes sense that there's a difference. I read that you can unset a header if you set its value to undefined

const bearerToken2 = jwt.sign(
{
    sub: 'R4jN64TINmS2Yy0NamHjaEH6Pq0u21eCOVXsaM1q0H20GH2mhBP4XmFwXUlcnXyv'
},
'lGQmeQJ9tEz0es3V91PdnOIb_IoUNCkvGMyAc4HC6g2-5ZzKeubqPQ',
{
    header: { typ: undefined }
});

VALUE = eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJSNGpONjRUSU5tUzJZeTBOYW1IamFFSDZQcTB1MjFlQ09WWHNhTTFxMEgyMEdIMm1oQlA0WG1Gd1hVbGNuWHl2IiwiaWF0IjoxNjUxODMyOTE5f Q.jEP-QI6JYZnLk50M-Af6T7QXPIm10CRhC0KV8l0pi0Q

Still no luck so I looked into the sign.js sourceCode

var header = Object.assign({
  alg: options.algorithm || 'HS256',
  typ: isObjectPayload ? 'JWT' : undefined,
  kid: options.keyid
}, options.header);

there I removed the "typ" property from the header than I get the following VALUE = eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJSNGpONjRUSU5tUzJZeTBOYW1IamFFSDZQcTB1MjFlQ09WWHNhTTFxMEgyMEdIMm1oQlA0WG1Gd1hVbGNuWHl2IiwiaWF0IjoxNjUxODMzMDcyfQ .oDkgJ1ARtqeSDUPaNqhbjJGHuT1piSKHHgj_PQSvcxQ

Maybe I completely misunderstood what https://jwt.io/ and jsonwebtoken do.

Hope someone can help me.
