Get 500 error on client side but 403 in terminal for the backend

To follow up on this… my issues turned out to be a bad formatted plugin config file. I had:

'users-permissions': {
  config: {
    jwt: {
      jwtSecret: env('JWT_SECRET'),
    }
  },
},

Instead of:

'users-permissions': {
  config: {
    jwtSecret: env('JWT_SECRET'),
  },
},

So it was merging the jwtSecret with the jwt options which get sent to jsonwebtoken. jwtSecret is not a valid option, so jsonwebtoken was throwing an error back to Strapi.
