Trouble using in typescript project

[mjgoeke]

I'm having trouble getting this plugin pulled in in the support/index.js in my Cypress (with typescript) project.

When clicking to run a test, the test runner ui shows

Oops...we found an error preparing this test file:

./cypress/support/index.js

 @ multi ./cypress/support/index.js

I've run npm install -D cypress-skip-and-only-ui and all the files seem intact. I've tried deleting node_modules\cypress-skip-and-only-ui folder and re-running the npm install to no avail.

Here are my plugins and support index.js files: plugins_index.js.txt support_index.js.txt

Do you need to see webpack.config too?

What am I missing/doing wrong here?
