Bug: _ctx is missing functions that are returned from the setup functions #1870

sevilyilmaz · 2022-11-16T16:55:43Z

Hi,
I started getting the error below after upgrading from 2.2.1 to 2.2.2.

    Received message:   "_ctx.hasIcon is not a function"

          209 |           props.countryCode.charAt(0).toUpperCase() +
          210 |           props.countryCode.slice(1),
        > 211 |       };
              |                   ^
          212 |     });
          213 |
          214 |     const hasIcon = () => Boolean(slots.icon);

Describe the bug
I do slot validations in the setup function, sometimes to hide certain HTML elements and sometimes for their content. I created a helper to capture the errors.

function testErrors(testBody) {
  /**
   * @see https://github.com/vuejs/vue-test-utils/issues/641#issuecomment-443651405
   * @see https://github.com/vuejs/test-utils/issues/1096
   */
  const spyError = jest
    .spyOn(global.console, 'error')
    .mockImplementation(() => {});

  testBody();

  spyError.mockRestore();
}

I write the tests like this:

it('throws an error', () => {
  testErrors(() => {
    expect(() =>
      // mount component
    ).toThrowError(ERROR_MESSAGE);
  });
});

When I upgraded to 2.2.2 I started getting the error above. It seems the functions that I use in the template are not being populated from the setup function.

I assume the problem that I'm having is related to this change 74c9af4

To Reproduce

<template>
  <div v-if="hasSlot('test')">
    <slot name="test"></slot>
  </div>
  <slot></slot>
</template>

<script>
export default {
  setup(_, { slots }) {
    const hasSlot = (slotName) => Boolean(slots[slotName]);

    if (!hasSlot('default')) throw new Error('The default slot is required');
    
    return { hasSlot }
  }
}
</script>

Expected behavior

The component should be able to use the functions that are returned from the setup function.

Hi @sevilyilmaz

Can you provide us a small repro online using https://stackblitz.com/edit/vitest-dev-vitest-qoiwy3?file=package.json&initialPath=__vitest__ ?

sevilyilmaz · 2022-11-16T19:40:51Z

Hi @cexbrayat
Upgrading to 2.2.3 didn't solve my issue. Here is the reproduction link: https://stackblitz.com/edit/vitest-dev-vitest-9qeea3?file=test/basic.test.ts

cexbrayat · 2022-11-16T20:03:41Z

👍 thanks

@xanf What do you think we should do in that case?

xanf · 2022-11-16T21:05:54Z

@cexbrayat let me investigate that

Theiaz · 2022-11-17T08:03:09Z

Hey,

had the same issue since yesterday. Got a minimal example repo to reproduce it. Have a look at the README and he commit history to reproduce the error and potentially fixes.

However, we got those errors since 2.2.3. Previous versions are working.

Edit: Maybe this post is more related with #1869

stephan-roolvink · 2022-11-17T08:13:28Z

I have encountered this same issue with version 2.2.3 on i18n. TypeError: _ctx.$t is not a function

cexbrayat · 2022-11-17T08:24:05Z

@stephan-roolvink @Theiaz Yes, you are probably encountering #1869 We already have a fix, we just need to merge and release it.

lmiller1990 · 2022-11-20T22:42:08Z

#1869 is out, can anyone encountering this issue try updating to 2.2.4 and see if that fixes it?

sevilyilmaz · 2022-11-21T08:26:55Z

@lmiller1990 I still have the error after bumping up to 2.2.4. Here is the updated repro link if it helps
https://stackblitz.com/edit/vitest-dev-vitest-ezvqg2?file=test%2Fbasic.test.ts

Theiaz · 2022-11-21T10:36:49Z

#1869 is out, can anyone encountering this issue try updating to 2.2.4 and see if that fixes it?

The fix is working at my example repo.

cexbrayat · 2022-11-21T10:49:09Z

@Theiaz 👍
I think it should work for @stephan-roolvink as well because you were in fact encountering another issue

The issue @sevilyilmaz has is another one, and we need @xanf feedback

xanf · 2022-11-21T11:09:08Z

Yeah, I'm still looking if we could fix it in vue core, because I'm still looking for non-ugly workaround in VTU

stefanlivens · 2022-11-22T10:07:47Z

we still have the same error. downgrading to 2.2.2 fixes it immediately... using a combination of options api and composition api in our project. and since 2.2.3 we get this problem: global mocks just disappear (in our case, we 'enhanced' the mount/shallowMount with mocks for all vue-i18n methods, so all our mount/shallowMount have this mocked vue-i18n methods, even adding a mocked $router just ... disappears...)

Theiaz · 2022-12-09T11:42:40Z

We are still investigating some strange behaviour together with setup-option and vue router (nested routing). Tests keeps failing, only rollback to 2.2.2 solves it.

I created an example repository on stackblitz.

sevilyilmaz · 2023-03-03T10:24:21Z

Are there any updates? I'm kind of stuck to v2.2.2 because of this issue.

lmiller1990 · 2023-03-05T22:25:14Z

Did we ever isolate the commit that broke this? That'd be the first step to finding a fix.

stefan-wiebe · 2023-05-26T15:04:33Z

FYI I have the same issue except with $setup.t, using script setup and vitest.
The earliest working version is v2.2.1.

kyrylo93 · 2023-07-03T13:42:07Z

I have this issue too (

kayijyc · 2023-07-04T14:37:07Z

FYI I have the same issue except with $setup.t, using script setup and vitest. The earliest working version is v2.2.1.

I have the same issue with <script setup />. I have downgraded to v2.2.1 and it worked. I've also tried v2.2.2 but it doesn't solve the issue.
I can confirm that the latest working version is v2.2.1 as @stefan-wiebe said.

It seems that my issue only happens when t (from vue-i18n) is being used directly in the template. If I extract the t() functionality in a computed property and use that computed property in the template, it works.

TypeError: $setup.t is not a function
<template>
      2|   <p>{{ t('title') }}</p>

I have this issue too, had to downgrade to 2.2.1 to get test utils to find my computed functions.
