Sails: TypeError: Expecting a function in instanceof check, but got #<bound>

[dularion]

When trying to change an existing user-record using a POST on localhost:1337/api/user/1 I get the following:

/Users/antonia/dev/projects/streama/streama-node/node_modules/sails-mysql/node_modules/mysql/lib/protocol/Parser.js:82
        throw err;

Any Idea what this may be about? Saving new records works fine..

I got a similar bug with my blueprint POST and PUT routes.
I dont have any particular example, but for every models (a simple Dashboard model for exemple) created with sails generate, the sails app crashes with this message:

/Users/nunja/Documents/Node/bakabase/node_modules/sails-mongo/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:757
      catch(err) { process.nextTick(function() { throw err}); }

The only workaround which works here is to override the create (or update) method in the DashboardController.

I am getting the same error, right after updating to sails 0.11.
I am also doing a PUT/POST to localhost:1337/api/user/1

[sgress454]

Hm, very weird. Seems like possibly a bug in that particular dependency. Try reinstalling Sails to get all the latest dependencies:

npm uninstall -g sails
npm cache clean
npm install -g sails

(might need to do sudo for these)

[dioptre]

This is because you may have a File.js model - rename it and try?!

[juanpasolano]

I don't understand what you are saying @dioptre.
@dularion is this happening to you from a brand new sails 11 app? or is it from updating one? Thanks

[sgress454]

@juanpasolano what @dularion is suggesting is that if you have a file called api/models/File.js, or some other reserved Node class, it may be causing a conflict when Sails globalizes the model. What models and services do you have in your project (in your api/models and api/services folders)?

[juanpasolano]

Thanks @sgress454. That is super clear, i will do that now
UPDATE:
Its solved for me :), I did have a File model and removing it worked.
Thanks @dioptre and @sgress454
In fact the error changed to

/Users/juan/Documents/juanpa/vetapp/sites/webapp/back/node_modules/sails/node_modules/sails-hook-sockets/node_modules/socket.io/node_modules/has-binary-data/index.js:30
         (global.File && obj instanceof File)

Now all POST/PUT request are working fine :+1:

Another way by not exposing defined models as global variables with "config/globals.coffee" below.

module.exports =
    globals:
        models: false
        services:   false

[chirag200666]

I got the same error. I can confirm this issue in versions 0.11.2 , 0.12.0, 0.12.1 .
Thanks @dioptre for the fix, it worked for me.
@sgress454 I think it can be a part of the documentation as adding a model named File can be pretty common. What do you think ?
