Description Samuel Padgett 2021-04-23 16:11:50 UTC
Running console in an old version of Safari results in the error:

TypeError: undefined is not a constructor (evaluating 'new Intl.RelativeTimeFormat(getLocale() || undefined)')

We're using `Intl.RelativeTimeFormat`, which is only available in Safari 14 and newer. See 

We should fall back to showing the full date in cases where the browser API is not available.

This is only an issue in OpenShift 4.8 and not a bug present in any shipped OpenShift version. This was introduced in https://github.com/openshift/console/pull/8490. The backport PR https://github.com/openshift/console/pull/8734 does not remove moment.js, so it doesn't use the problematic API.

Comment 1 Samuel Padgett 2021-04-23 16:18:03 UTC
Note to QE: Bug 1952635 prevents console from showing content in Safari as well. Even with this bug fix, you will not be able to use console in Safari until the other bug is fixed. You can verify that the runtime error has been addressed by inspecting the JavaScript console or checking that at least the masthead renders.

Comment 3 Yadan Pei 2021-04-26 01:49:00 UTC
Due to bug 1952635 console is only showing main header which is expected now(without fix)

However I still see a total blank page returned and a different JS error on 12.0.2, see screenshot

Assigning back for confirmation, this is checked against 4.8.0-0.nightly-2021-04-25-183122

Comment 5 Samuel Padgett 2021-04-26 15:30:18 UTC
`Promise.allSettled` seemed to have been added for dynamic plugin loading.

❯ rg -F 'allSettled'
50:    // The promise returned by Promise.allSettled() never rejects; no need for catch-or-return.
52:    Promise.allSettled(

2: * Unwrap the result of `Promise.allSettled` call as `[fulfilledValues, rejectedReasons]` tuple.

It looks like Safari 13 or newer is available for all supported versions of macOS. You have to go back to Sierra (5 versions ago) to require Safari 12. Given this, I think it's fair to ask users to upgrade Safari to a supported version. Moving back on ON_QA.


Comment 6 Yadan Pei 2021-04-29 02:39:32 UTC
Hi Sam,

I got these js error and blank page using Safari 12(as screenshot shows), am I using the wrong version to verify the bug?

Comment 7 Samuel Padgett 2021-04-29 15:47:37 UTC
Hi, Yadan. Please use Safari 13 to verify.

* Safari 14 is the latest and fully supported.
* Safari 13 is no longer supported by Apple and is best effort support for OpenShift. The bug fix addresses the runtime error for Safari 13 only.
* Safari 12 is quite old and no longer supported by Apple. You'd have to be running macOS Sierra to not be able to upgrade to at least Safari 13. High Sierra, Mojave, Catalina, and Big Sur have all been released since macOS Sierra, so it's an old macOS version and no longer supported.

Visit OCP console with Safari 13.1.2, now console is loaded successfully, see screenshot

Verified on 4.8.0-0.nightly-2021-05-06-162549 and Safari 13.1.2
