[ERR_INVALID_CHAR]: Invalid character in header content ["x-cypress-file-path"] #25839

Nutcracker52 · 2023-02-16T03:36:18Z

Current behavior

#25273 related to this closed issue and I can confirm this is happening and it's pretty annyoing.

Error Code pops

TypeError [ERR_INVALID_CHAR] [ERR_INVALID_CHAR]: Invalid character in header content ["x-cypress-file-path"]
    at ServerResponse.setHeader (_http_outgoing.js:561:3)
    at onRequest (C:\Users\Nutcracker52\AppData\Local\Cypress\Cache\8.3.1\Cypress\resources\app\packages\server\lib\file_server.js:37:7)

test I am trying to run

  it('validation email sent and user can confirm', () => {
    cy.getEmail(Cypress.env('emailAddress'), 'Welcome to ABC', true).then(email => {
      expect(email.subject).equal('Welcome to ABC')
      const validateUrl = getEmailLink(email.html, `${Cypress.env('appUrl')}/account/verify?code`, '"')
      cy.visit(validateUrl)
      cy.contains('you are now ready to login!', { timeout: 30000 })
    })
  })

I am reading emails from an API and check that email has been received and then email contains a link and click that link

Desired behavior

Cypress shouldn't throw any errors while test is running. This completely crashes Cypress and I have to run tests again.

To avoid the error I had to add cy.visit command as first line to the code. which is not necessary.

Test code to reproduce

please use the given code above.
get email is a function that we designed to get emails from an api.
I cannot share it.

@Nutcracker52 what is the value of validateUrl when this error occurs? I'm guessing it contains some special characters that we aren't handling correctly in the internal HTTP file server.

@Nutcracker52 what is the value of validateUrl when this error occurs? I'm guessing it contains some special characters that we aren't handling correctly in the internal HTTP file server.

I can confirm at least special characters in paths can cause this problem.
I cloned easy-markdown-editor in a folder, which has an ancestor folder called Umaĵo, and this error occurred when I tried run its tests. after renaming the folder from Umaĵo to Umajho, that error goes away.

(OS: macOS 12.6.3; cypress version: 10.11.0)

mjhenkes · 2023-03-13T18:48:10Z

@umajho, I attempted a recreation here: https://github.com/mjhenkes/issue-25839 but i think my one test is too simplistic.

Which tests do you see failing in easy-markdown-editor?

umajho · 2023-03-15T06:56:47Z

Cypress just exited while running the first test it picked.

AtofStryker · 2023-03-16T17:22:53Z

I'm hoping to give @mjhenkes 's repro a shot hopefully next week trying to run these tests with a different language configured in a ubuntu VM, or a special character in a folder name being used.

AtofStryker · 2023-03-23T18:03:52Z

@mjhenkes I wasn't able to reproduce with your reprod but I was able to reproduce with easy-markdown-editor inside an ubuntu VM with the directory with a special character. I could not reproduce without the special character in the directory. I am going to go ahead and route this since we can reproduce the issue

Sitronik · 2023-03-31T09:31:43Z

I had the same error, it turned out I forgot to initialize the environment variables on the command line that are used in cypress.config.ts

minsoo-web · 2023-07-30T12:34:32Z

I had the same error

In my case, it happened in the process of loading the local html file.

I didn't understand exactly why,
I found out that the src path of the img tag was caused by getting it from the assets folder, and the image file was named Korean.

The test could be executed normally by solving as follows.

Before

<img
  src="./assets/image/coffee/제주_비저링_콜드_브루.jpeg"
  width="200"
  height="200"
/>

After

<img
  src="./assets/image/coffee/coffee1.jpeg"
  width="200"
  height="200"
/>

andrew-hurskiy · 2023-09-20T12:22:57Z

If somebody still faces such issue, solution might be to encode url, before giving it to Cypress.
