cypress adds __/ while using cy.visit()

I am trying to use cy.visit('https://web.telegram.org'); but instead it hits https://web.telegram.org/__/

Can you try setting this config option in your cypress.json or elsewhere:

{
	"experimentalSourceRewriting": true
}

already tried that but didn't work 😞

Cypress issues a request to https://web.telegram.org/__/ in order to load Cypress from that domain. It's not actually sending a request to that domain, it's really just requesting an internal Cypress document. You can read more about why we have to do that here.

Looks like Telegram is using a service worker which is preventing Cypress from working properly (you can test by manually removing it and refreshing, which causes everything to work properly). This issue has been reported in #702, and there are a number of workarounds presented in that thread, so I'd suggest trying some of those out. (Closing this issue as duplicate)

If you're trying to automate Telegram, they do have some official APIs that might work better than Cypress for that purpose.
