Missing Error State in SignJWT (?)

[jvanalst]

Describe the bug

TypeError: Cannot read property 'crit' of undefined
at SignJWT.sign (C:\Users\jvana\Desktop\Work\edrego\node_modules\jose\dist\node\cjs\jwt\sign.js:17:42)

To Reproduce

Code to reproduce the behaviour:

await new SignJWT({
    customer: 'abc123',
}).sign(crypto.createPrivateKey(config.local.privatekey));

Expected behaviour

It should throw an error, but I think because the _protectedHeader isn't initialized it never makes it to the actual throw.

Environment:

• jose version: v3.13.0
• affected runtime is: Node.js 14.16.1

Additional context
Add any other context about the problem here.

• the bug is happening on latest jose too.
• i have searched the issues tracker on github for similar issues and couldn't find anything related.
