Cypress detected that you returned a promise from a command while also invoking one or more cy commands in that promise.

I'm trying to intercept all matching requests during my entire integration test pass in order to trace and report some performance stats from Cypress to OpenTelemetry. I'm getting the following error and the code in question is below as well. Any advice would be appreciated!

Error:

Cypress detected that you returned a promise from a command while also invoking one or more cy commands in that promise.

The command that returned the promise was:

> cy.visit()

The cy command you invoked inside the promise was:

> cy.task()

Because Cypress commands are already promise-like, you don't need to wrap them or return your own promise.

From setupNodeEvents in cypress.config.js:

      on('task', {
        startSpan({ name }) {
          return new Promise((resolve, reject) => {
            const span = tracer.startSpan(name);
            resolve(span.spanContext());
          });
        },

        endSpan({ spanContext, status, duration }) {
          return new Promise((resolve, reject) => {
            const span = tracer.startSpan(spanContext);

            span.setAttribute('http.duration', duration);
            span.setStatus({ code: status });
            span.end();

            resolve();
          });
        },

From cypress/support/e2e.js:

beforeEach(() => {
  cy.intercept('/graphql', (req) => {
    const startTime = performance.now();

    cy.wrap(
      cy.task('startSpan', { name: `${req.method} ${req.url}` })
        .then((spanContext) => {
          req.continue((res) => {
            const duration = performance.now() - startTime;
            const status = res.statusCode === 200 ? 1 : 2;

            cy.task('endSpan', { spanContext, status, duration });
          })
        })
    )
  });
});

Lastly here is a small test written to test it:

  it('*** testing ***', () => {
      cy.login('user@domain.com'); // this is a custom command that logs in the user with a password coming from an environment variable
      cy.visit('/projects');
  });
