Intermittent QRDA upload error in Chrome

[pelargir]

This appears to be an issue specific to the Chrome browser, but I wanted to document it here to see if anyone else has experienced it.

In Chrome, when I click the "Upload Results" button and select a QRDA Cat I zip file or Cat III XML file, Cypress will intermittently respond with this error:

Mongoid::Errors::InvalidFind (
Problem:
  Calling Document.find with nil is invalid.
Summary:
  Document.find expects the parameters to be 1 or more ids, and will return a single document if 1 id is provided, otherwise an array of documents if multiple ids are provided.
Resolution:
  Most likely this is caused by passing parameters directly through to the find, and the parameter either is not present or the key from which it is accessed is incorrect.):

Apparently, the form attributes aren't getting sent in the POST to /test_executions (which is why the CSRF warning also gets displayed). This happens roughly 75% of the time. The remaining 25% of the time, the form attributes are sent with the POST and the upload completes successfully.

This doesn't happen in Safari or Firefox. In these browsers, the form attributes are sent 100% of the time.

There is a known bug in Chrome where form attributes aren't sent, but I'll have to do some additional research before recommending a possible workaround.

Matt,

What version of Chrome are you using? I pretty much only use chrome and have not seen this or been able to reproduce it.

I'm on version 28.0.1500.71

Maybe one of the extensions I'm using is interfering with the page. I'll try disabling all of my extensions and see if the problem persists.
