Validation error "must be an object"

[kamranhossain]

This is the error I find in terminal of my code. I cant resolve this exception. "Exception while invoking method 'myway.enterName' Error: The first argument of validate() or validateOne() must be an object". In console "Error invoking Method 'myway.enterName': Internal server error [500]" this error is shown.

Thnx in advance.

I am also getting the same error:

Exception while invoking method 'methodName' Error: The first argument of validate() or validateOne() must be an object

The error is caused when I attempt to call a method without an object

// example
new ValidatedMethod({
    name: 'methodName',
    validate: new SimpleSchema({ text: { type: String }}).validator(),
    run: function(data) {}
});

Meteor.call('methodName'); // causes Error: The first argument of validate() or validateOne() must be an object
Meteor.call('methodName', {}); // validation error (appropriate behavior)

Edit: I thought this was causing my server to restart, but it was a different issue. This behavior is appropriate, and what is causing it was a call to a method that expects an object. Anyone else seeing this error should check to make sure they are sending the right arguments to a method call.

I would like to be able to call a ValidatedMethod without an object argument when my method definition takes no arguments.

I do understand that I could simply define these kinds of methods with the regular Meteor.methods call, but I would prefer to define all methods the same way for consistency's sake.

I'm guessing this is as designed. I had the same issue but the discussion above gave me the extra "a-ha" that I needed.

You need to make sure that you pass an object when you're calling you're meteor method, because validatewill only work on objects, not single arguments.

So:

Meteor.call('AwesomeMethod', someArgument) // won't work and will result in the error in your terminal
Meteor.call('AwesomeMethod, {someArgument} // will work, because now you are putting the argument in an object, by putting {} around it

this spoked me for a bit so i thought i'd share this.

Meteor.call('AwesomeMethod, {key: value}, callback )
