I have a function to protect the route. Use as follows

const authMiddleware = async (req, res, next) => {
    const token = req.header('Authorization')?.replace('Bearer ', '')
    if(!token) return anauthorized(res)

    jwt.verify(token, JWT_SECRET, (err, decoded) => {
        if(err) {
            console.log(err)
        }

        console.log(decoded)
        next();
    })
}

I can get everything right. jwt.Verify gives me an error

JsonWebTokenError: invalid algorithm

I have tried to implement several solutions, but without success. What I could do?

javascript node.js web-application jwt

  • The JWT has, in the header, a definition of the algorithm that was used when signing. You probably created the token with an algorithm that is not supported by the function verify you are using. How you are creating the token?

  • This token comes from the login with google, who generates it. I just send the same in the header of fetch.
