How to trace meteor bug?

I go an error which looks like this Error msg.

First I think is something went wrong with my component,
but I remove all component from index.js, the error is still stand.

Then I try to remove all the publication from /server/main.js, but is useless.

I put a break point on the main.js:171, which the string pass into the function is “Meteor._setImmediate.0.696021492825549.2”

I have no ideal where this come from and how to fix it.

thanks for reply.

Please post your code from main.js.

Sorry for the unclear question.
The main.js is the file that Meteor had been build.

OMG, I found the question, it cause by my browser plugin…
