Error: secretOrPrivateKey must have a value

[freder]

I'm trying to get uppy-server to work with dropbox:

// ...

expressApp.use(bodyParser.json());
expressApp.use(session({ secret: '...' }));

// ...

const options = {
    providerOptions: {
        dropbox: {
            key: '...',
            secret: '...',
        },
    },
    server: {
        host: `localhost:${PORT}`,
        protocol: 'http',
    },
    filePath: './uploads/'
};
expressApp.use(uppy.app(options));

// ...

but after connecting to dropbox / redirecting to http://localhost:3000/dropbox/callback I get this error:

looks like req.uppy.options.secret is undefined here https://github.com/transloadit/uppy-server/blob/master/src/server/controllers/callback.js#L24

you need to set the secret option like so:

const options = {
    providerOptions: {
        dropbox: {
            key: '...',
            secret: '...',
        },
    },
    server: {
        host: `localhost:${PORT}`,
        protocol: 'http',
    },
    filePath: './uploads/',
        secret: 'my-secrety-secret'
};

this secret is used by the server and is different from that provided by the dropbox api.

right, I just figured that out. — you should probably document that, since secret is not mentioned in the example in the readme.

[ifedapoolarewaju]

it's mentioned in the docs, see https://uppy.io/docs/server/#Options

hmm, I must have overlooked that. thanks you, @ifedapoolarewaju
