Bug

What is the current behavior?

When I upgraded my version of testcafe from 0.18 - 0.20, I started seeing errors as soon as I tried to execute an action in my testcafe test. The error was in new relic's code.

Uncaught TypeError: Cannot read property 'cancelled' of null

The action I tried to take was just await t.typeText(Selector('.username', 'foo')

What is the expected behavior?

The app should not crash in my third party code.

How would you reproduce the current behavior (if this is a bug)?

Run a test with newrelic's browser code in the app.

Provide the test code and the tested page URL (if applicable)

await t.typeText(Selector('.username', 'foo')

I can't provide the app as it's internal. But it's just a plain react app and index.html contains the code provided by new relic to run in your browser.

Specify your

• operating system: OS X High Sierra
• testcafe version: 0.20.5
• node.js version: 9.11.1
