JsonWebTokenError: jwt malformed

[replete]

Encountered this error while investigating other issues I've been having around this codebase, I am reporting it here as someone had this problem in the other repository.

Environment

• node v16.12.0
• npm 8.1.0
• MongoDB 5.0.3 community edition installed from homebrew
• macos catalina 10.15.7

Repro

git clone git@github.com:TomDoesTech/Testing-Express-REST-API.git
cd Testing-Express-REST-API
npm i
(make sure mongodb is ready)
npm run dev
(send 'Create User' request in Postman)
(successful response in postman:)
{
    "email": "test@example.com",
    "name": "Jane Doe",
    "_id": "6174b21643dd23a0be37c83b",
    "createdAt": "2021-10-24T01:08:38.462Z",
    "updatedAt": "2021-10-24T01:08:38.462Z",
    "__v": 0
}

Then follows this error in the console:

@tomanagle Cheers Tom, didn't stop me but I was just reporting it here as it probably was tripping other people up.

@replete I am not using postman, as demo'd in the video. I am just getting it randomly and my browser is in a refresh loop. Tried going back to working commits but it's still happening. Any suggestions?
