Is there an error message shown above the stack trace?

Yes sorry @zodern forgot to copy the error at the top. Here it is directly from webstorm debugging console

@zodern I'm seeing the same issue with versions 2.36.0 and 2.36.1. Version 2.35.0 is ok.

I'm seeing similar issues. I am on:

montiapm:agent@2.36.1

Unclear what is causing this to happen.

This is the line causing the issues:

const Subscriptions = new Mongo.Collection('subscriptions');
// this line throws an error for some reason:
return Subscriptions.findOne(selector, options);

Thanks @elie222. When is this code run (server startup, method, publication, etc.)?

So it's a Meteor method that calls an ES6 async function. It turns out that this function doesn't use await at all so I just made it non async and all works.

I'm worried this is still an issue in other places however. I don't remember how this all works with Meteor, but did this issue arise because I had to wrap the async function in Meteor.wrapAsync, or is it in fact a bug with this package?

I can confirm the issue does not exist on montiapm:agent@2.35.0.

it's a real problem, our publications just crash without knowing the cause @@

Any updates on this @zodern ? For us, it happens just after starting the app when subscribing to any publication that uses publish-counts

It is fixed in version 2.37.0

This is still a problem for me with version 2.37.2 - had to downgrade to 2.35.0

I am getting a similar error as above. But I can't downgrade to 2.35.0 because my other packages require email@2.0.0. So, I'm not able to use Monti APM until this is resolved. Which is a drag, because I really want to pay you $5/month use it!

If you want to reproduce this error, you can download the RadGrad2 system from:

https://github.com/radgrad/radgrad2

  1. CD into the app/ directory
  2. meteor add montiapm:agent
  3. meteor npm install
  4. meteor npm run start

Then try to retrieve http://localhost:3200 in a browser. That will trigger this error.

Thanks for the reproduction @philipmjohnson. I tried it, and did not encounter the error.

I published version 2.39.1-beta.1 which will log the full trace when this error happens. You can try it with meteor add montiapm:agent@2.39.1-beta.1. When it logs the trace, please share it here.

@philipmjohnson until this is fixed, you can modify the .meteor/packages file to force it to use email@2.0.0.

email@2.0.0!
montiapm:agent@2.35.0

Older versions of the agent are compatible with email@2

@zodern I promise you, it was busted yesterday!

Anyway, I started over with montiapm:agent@2.39.1-beta.1, and now everything appears to be working.

Thank you so much for your quick response! Already worth way more than the $5/month!

Just added montiapm:agent@2.40.1 to my project and getting the same error:

NOTE:
mdg:meteor-apm-agent package is still in the project, not sure if that might be the problem

NOTE 2 - RESOLVED: looks like it was the problem to have the mdg package there, maybe it should be in the readme

This is fixed in version 2.41.0. It checks if your app is using any other APM agents based on Kadira, and logs a warning.
