Content-Type and other headers missing in gRPC requests in Cypress with Connect-ES

[robertwenquan]

Current behavior

In Cypress E2E test, a few HTTP headers are not set.
Specifically, Content-Type header is not set along with other headers with running with cypress that lead to 415 Content not supported error returned from the API gateway.
The request doesn't reach the API server bacause of this.

Desired behavior

Content-Type and other headers are set just like it behaves in a normal Chrome browser.

Test code to reproduce

describe("LoginForm component test", () => {
    it("normal login", () => {
        cy.visit("/login");
        cy.get("[data-cy='input-email']").type("[[email protected]](mailto:[email protected])");
        cy.get("[data-cy='input-password']").type("password.123{enter}");
    });
});

Does it worked in previous cypress version ???

Does it worked in previous cypress version ???

seems not related to previous version.

this was cleared by either:

1. changed the ConnectTransport to WebTransport (grpc-web)
2. removed experimentalFetchPolyfill: true while keeping the ConnectTransport

In the end we changed to WebTransport and disabled the experimentalFetchPolyfill as well.

Hey @jennifer-shehane any opportunity to get some attention from Cypress? I am trying my best to figure out the situation but I am not sure what else to try. The changes suggested by @robertwenquan didn't work me
