cy.intercept() TypeError: mime.getType is not a function #290

Hi team, we upgraded from Cypress 8.7.0 to Cypress v9.4.1 as this is the latest supported in Browserstack according to the docs https://www.browserstack.com/docs/automate/cypress/limitations

One of our tests uses cy.intercept and after the upgrade we noticed the following error in that test:

TypeError: An error was thrown while processing a network event: mime.getType is not a function
  TypeError: mime.getType is not a function
      at ret (/root/app/packages/server/lib/controllers/xhrs.js:120:19)
      at parseContentType (/root/app/packages/server/lib/controllers/xhrs.js:124:14)
      at /root/app/packages/net-stubbing/lib/server/util.js:106:107
      at Generator.next (<anonymous>:null:null)
      at fulfilled (/root/app/packages/net-stubbing/lib/server/util.js:5:58)

After debugging, I found out that the problem might be the version of the mime package, as it is used to parse the response mime type. Version 2.4.4 introduced breaking changes (like renaming lookup in favor of getType), but what is weird is that this version upgrade (from 1.6 to 2.4.4) was made in Cypress v4.3.0 so...not sure what's going on.

Any help will be much appreciated. Thank you in advance.

We also encountered the exact issue when using Cypress 9. Reverting back to Cypress 8 in browserstack.json resolves the issue.

Can you try with the latest version of Cypress - 9.6.1 which is being supported by BrowserStack? Is this issue encountered when you execute locally on your machine?
