We have changed the validators used for the sign method. Take a look to the first item in the migration guide: https://github.com/auth0/node-jsonwebtoken/wiki/Migration-Notes:-v7-to-v8

We use lodash now, take a look to this function: https://lodash.com/docs/4.17.4#isPlainObject

Anyway I think we should communicate better that error, it could say something like "expected payload object to be a plain object" or similar.

Can you share the content of doc?

@ziluvatar : I've added a PR to change the wording.

[ziluvatar]

PR was merged. It's on v8.1.0

Can this be fixed by simply adding .toJSON()?

[kedrovski]

You can try .toObject() -> jwt.sign(doc.toObject(), jwtSecret);

[NodeJoSe]

@kedrovski or @UNADYNE solution works fine but i suggest you to use: JSON.parse(JSON.stringify(doc)) if your doc object comes from diferent sources, for example:

You could have to pass diferent "doc" objects, one returned from mongoose and another defined by you like this:

doc = { name: 'foo', description: 'bar' }

If you use .toJSON() or .toObject() You will get a "doc.toObject/doc.toJSON is not a function" error with the doc you defined manually.

wont there be a performance issue using json stringify with json parse ? but yeah toJSON() or toObject() both comes as undefined on the object
