Detecting error ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION in Chrome

[Peetzer]

I'm testing a specific error in Chrome where downloading a file where the filename is unquoted and contains a comma in the stubbed response.

After a file is clicked an error occurs when I pause my spec and check all calls,

Failed to load resource: net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION

Then my cy.wait is called in my test returning a response with statusCode 200 ?

How can I check if an error occurred?
