Do no support throw exception inside method call

[weilitao]

Hi,

When I throw an exception in Meteor method, like that:
throw new Meteor.Error('abcdef');

in Meteor-Unity side, an exception occurred below:

System.ComponentModel.BaseNumberConverter.ConvertFrom (ITypeDescriptorContext context, System.Globalization.CultureInfo culture, System.Object value)

So how to support catch exception during method call?

Could you show me some more code to help me reproduce the issue?

Hi, below is code sample:

Meteor side:

export const play = new ValidatedMethod({
  name: 'sample',
  validate: null,
  run() {
    throw new Meteor.Error('test');
  },
});

Meteor-Unity side:

// Create a method call that returns a string
var methodCall = Meteor.Method<SampleResponse>.Call ("sample");

// Execute the method. This will yield until all the database side effects have synced.
yield return (Coroutine)methodCall;

if (methodCall.Error != null) {
  var response = methodCall.Response;
  Debug.Log(string.Format("Method response:\n{0}", JsonWriter.Serialize(response)));
} else {
  Debug.Log(methodCall.Error);

And if I turn on log Meteor.Connection.Logging = true;, log from DDP shows:

{"msg":"result","id":"sample-1","error":{"error":"test","message":"[test]","errorType":"Meteor.Error"}}
UnityEngine.Debug:Log(Object)

Thanks for the additional code, I will fix this issue.

Thanks, do you have any plan when the bug would be fixed :)
