Research direction

Start with the header construction shown in the issue and reproduce the supplied jwt.sign call, then compare the resulting token with the Python JWT library and RFC 7519 section 3.1. Verify whether header property order affects interoperability; done means a focused reproduction and clear cross-library result, with a regression test if a defect is confirmed.

Written by the indexing model from the issue text.

Description

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

I think it's need to swap alg and typ fields

https://datatracker.ietf.org/doc/html/rfc7519#section-3.1
or order of properties must according to of order of options in 'header' parameter

const header = {"typ": "JWT", "alg": "HS256"}
const token = jwt.sign(payload , JWT_KEY, {header: header})
