Current behavior

When I run my automation it returns an unknown error. and only in the Cypress browser on Chrome or any other it gives this error, if I log in outside of the browser that Cypress opens it opens the normal application screen.

ERROR:

Desired behavior

You should be able to return to the login scenario without showing this error and should open the normal screen as shown in the image.

@francllinrios Cypress has a proxy that pulls all the headers off of the requests and resets them (if needed). This erroring is surfacing that there is an invalid HTTP header since this error is being thrown when we set it from Node's https://www.geeksforgeeks.org/node-js-http-validateheadername-method/

If this is your website: http://salesportalcli.hml.prodatamobility.com.br/, you have an invalid HTTP header that your setting and those requests will silently not go through. You need to remove the extra character in the expires header to fix this. So this is highlighting a bug on that website.

That being said, Cypress should handle this better. Perhaps we should validate that the HTTP headers are correct before resetting them? Or just catch and ignore and errors that are thrown here? Probably second option makes more sense. https://github.com/cypress-io/cypress/blob/fix-flake-on-launchpad-ui/packages/proxy/lib/http/response-middleware.ts#L332

@jennifer-shehane Hi! After some time spent reproducing the bug i managed to do it. I can make cypress raise the error with the visit command but the request command still goes through and I'm still trying to understand why. As to the solution, i followed your suggestion and just ignored the error but shouldn't cypress inform that the header is invalid? Maybe give some type of warning in the console? I'm interested in creating a PR to fix this.

@BernardoSousa03 Yah, we should handle this better I think.
