Query parameters on entry point JS files causes error Uncaught (in promise) TypeError: Cannot read property 'data-opts' of undefined

[perrygovier]

Stencil version:

 @stencil/core@1.2.1

I'm submitting a:

[x] bug report
[ ] feature request
[ ] support request => Please do not submit support requests here, use one of these channels: https://stencil-worldwide.herokuapp.com/ or https://forum.ionicframework.com/

Current behavior:

On Ionicframework.com, we include an md5 checksum query parameter to bust the cache of script includes. Doing this on the new module/nomodule script that I am warned to start using causes the following error:

Uncaught (in promise) TypeError: Cannot read property 'data-opts' of undefined
    at U (p-36d52602.js:1)
    at ionic-site-components.esm.js?v=4f2d1375934be104d1d77f8e2cc4648b:1

Expected behavior:

Stencil should bootstrap and hydrate like it does with the legacy script tag

Steps to reproduce:

Related code:

Add query parameters to the script tags stencil instructs you to use. Something like

<script type="module" src="/js/stencil/ionic-site-components/ionic-site-components.esm.js?v=4f2d1375934be104d1d77f8e2cc4648b"></script>
<script nomodule="" src="/js/stencil/ionic-site-components/ionic-site-components.js?v=084d3915fedb423feae090748bfa6ffe"></script>

Other information:

You can reproduce this in the ionic-site repo by swapping out the comments on these lines and restarting the watch script.

The lack of import.meta in Edge requires scripts to find themselves in the DOM to figure out their absolute location, the query must be breaking that

I get this when trying to use Stencil inside Shadow DOM. @perrygovier did you solve this in the end??

[perrygovier]

@noisyscanner manu's fix resolved this for me. Are you on the current version of stencil? Is it possible to not use query parameters in your URL?

[noisyscanner]

Actually had the same issue without query params in the URL, but just from trying to render it inside shadow root.

[biirus]

Yeah, I have the same issue. My url has no query params:

<script type="module" src="https://example.com/minds/dist/minds/minds.esm.versioned.js"></script>
<script nomodule src="https://example.com/minds/dist/minds/minds.versioned.js"></script>

versioned comes from my kinda cache invalidation system.

p-8107f8fd.js:2 Uncaught (in promise) TypeError: Cannot read property 'data-opts' of undefined
    at L (p-8107f8fd.js:2)
    at minds.esm.versioned.js:2

If I place data-stencil-namespace="minds" to the script tags, error disappears.

Hey everyone, today I got the same problem while I was refactoring my code. ( Your problem could be PascalCase || CamelCase)

Wrong one:

<script type="module" src="/build/PwcMap.esm.js"></script>
<script nomodule src="/build/PwcMap.js"></script> 

Correct one:

<script type="module" src="/build/pwcmap.esm.js"></script>
<script nomodule src="/build/pwcmap.js"></script> 

Be careful using Replace All 💀

Cheers

@noisyscanner I'm getting this same issue. Specifically from trying to use an external component in a shadow DOM component. Did you happen to find a solution/way around this?

[erichstark]

@manucorporat I have got the same error when adding version of the build into url.

/my-components/my-components.202007.esm.js

Is that a problem for stencil?

[noisyscanner]

@ElectricDanDan unfortunately not - I have not used Stencil for a while I am afraid :/
