Safari: Uncaught object "[object Object]" was thrown. Throw Error instead.

What is your Test Scenario?

This error occurs on a number of tests… but the easiest one is navigating to a url that redirects.

What is the Current behavior?

Similar to #6593, I’m getting an uncaught object error in Safari. I’m suppressing JS errors and uncaught errors… but my tests are still failing.

What is the Expected behavior?

I can navigate to the desired page, and no error is thrown once the page loads

Hello,

Thank you for your research, we’ll review @rob4629’s PR.

I tried to prepare a pull request but I’m failing at creating a test case because it’s impossible to install IE11 and I’m running macOS: Error: Cannot find the browser. "ie" is neither a known browser alias, nor a path to an executable file.

But I made a patch instead that you can use to fix the error locally while we’re waiting for testcafe @rob4629:

testcafe_fix_6624.patch.zip

Put this into your package.json:

"resolutions": {
    "testcafe": "patch:testcafe@latest#./patches/testcafe_fix_6624.patch"
  }

unzip the file and put it into a folder called patches relative to your package.json and run yarn install You might have to replace latest in the resolution with whatever version you have pinned of testcafe.
