cy.wait() always gives a timeout error: No request ever occurred.

[t-zander]

Current behavior:

I am just following he tutorial at your site and there is a part when cy.wait('@alias') is shown.

On the video it worked fine, However I always getting an error

CypressError: Timed out retrying: cy.wait() timed out waiting 5000ms for the 1st request to the route: 'create'. No request ever occurred.

I have tried it both in my project and in your completed tutorial project
The error is present in both cases.

Here is an image
Request is going

When I don't use cy.wait() it seems to work fine

Can you help me with this please?

Desired behavior:

cy.wait should for the request to resolve

@t-zander thanks for opening an issue with screenshots. In the DevTools, can you fetch the type of the request - is it XHR or fetch? Because currently Cypress can only spy / stub / wait on XHR requests See the warning in https://docs.cypress.io/api/commands/route.html#Syntax and a couple of workarounds in that case

[t-zander]

It's weird but error happened with syntax like cy.route('POST', 'url')
While in syntax like

cy.({
method: ....
})

Its gone.

Can you provide the full test code please?

Hi, sorry, it seems like the problem came again. I will share the code. (Sorry if something is wrong with it, but I just followed your tutorial movies)
I have a setTimeout() to imitate a network delay in all below cases

This way it works okay

context('With no todos', () => {
    it.only('saves new todo', () => {
      cy.visit('/')
      cy.server()
      cy.route({
        url: 'api/todos',
        method: 'POST'
      })
      .as('create');

      
      cy.focused()
        .type('buy milk')
        .type('{enter}')

      cy.wait('@create')
      
      cy.get('.todo-list')
        .should('have.length', 1)
    })
  });`

This way I have failing test (sometimes its working hovewer). In failing case it gives a timeout error
and says

No request ever occurred.

However, in panel I can clearly see xhr requests

context('With no todos', () => {
    it.only('saves new todo', () => {
      cy.visit('/')
      cy.server()
      cy.route('POST', 'api/todos')
        .as('create');

      
      cy.focused()
        .type('buy milk')
        .type('{enter}')

      cy.wait('@create')
      
      cy.get('.todo-list')
        .should('have.length', 1)
    })
  });

Now if I have consequent requests like these it also gives me an error

context('With no todos', () => {
    it.only('saves new todo', () => {
      const items = [
        {text: 'Buy milk', expectedLength: 1},
        {text: 'Buy bread', expectedLength: 2},
        {text: 'Buy butter', expectedLength: 3}
      ]
      cy.visit('/')
      cy.server()
      cy.route('POST', 'api/todos')
        .as('create');

      cy.wrap(items)
        .each((item) => {
          cy.focused()
            .type(item.text)
            .type('{enter}')
  
          cy.wait('@create')
          
          cy.get('.todo-list')
            .should('have.length', item.expectedLength)
        })
    })
  });

@t-zander The error you posted looks unrelated to the original issue you opened correct? I don't see any failure during the cy.wait() in the example.

[t-zander]

@jennifer-shehane
The second example sometimes gives tmeout error.
Third one is not directly connected but iit has to do with cy.wait()
May you please give me a hint why it may happen?(I mean third example)
thank you very much in advance

[benmonro]

@jennifer-shehane my colleagues are seeing this as well. any updates here?

[jennifer-shehane]

We'll need a reproducible example in order to look into this further.

[linture]

meeting this error, too...
Is there any solution?

[Pidz-b]

What can be the issue is the api/todos.
I had a similar issue where I waited for /oauth/v2/token/, apparently the call was to /oauth/v2/token.
The slashes before and after seem to matter.
Check if your call is to api/todos.

I guess not, as the path always starts with a slash right?

[jennifer-shehane]

Unfortunately we'll have to close this issue if no reproducible example is provided. Can anyone provide a way to reproduce this?

[alexsasharegan]

I just ran into this error, and this comment was the clue. I wasn't specifying the request method POST. I was under the assumption it matched any method to the url. That was the core of my problem.

Without a method:

With the method:
