Additional environment details

• SPFx version: 1.15
• Node.js version: 14.21.3
• New Lists interface

Describe the bug / error

On one specific Custom list only the SPFx extensions do not load. Works well on other lists and, strangely, works in Firefox.
When it doesn't work, the following lines are found in Console for each one of the extensions:

"A preload for 'https://storage.infowisesolutions.com/ufspfx/v1400/infowise-design.js' is found, but is not used due to an unknown reason."

Steps to reproduce

Not sure how to reproduce, but it consistently doesn't load on a particular list, but works on all the other lists within the same site, with or without the new Lists interface. This is a simple SPFx list extensions that adds some buttons to the toolbar.

This is the error:

Expected behavior

Loads on all lists in the site.

I would just add that we have also been experiencing similar issues with this meaning that customers are unable to perform functionality.

I did see a closed issue with relation to embedded pages for Command Set #10057 as this is a fairly new issue that has been closed and whether this had an impact causing the above?

[vladigubler]

As far as I can see, it affects certain lists, but not others. I can't see any difference between the lists, same template, same everything. It is persistent though. The affected lists stay affected, no matter what I do.
The only (imperfect) workaround is to add a custom column to the view, which forces the regular, not MS Lists, interface.

Thanks folks! We have a fix for the issue, and just need to evaluate our options for rolling it out. Workaround would be to visit the list/library in "full" mode (ie: not in a web part).

[vladigubler]

We are visiting it in full mode, we don't use web parts for this. It is an extremely wide-spread issue and I feel it's growing every day, probably as more tenants get the newest UI.

[vladigubler]

Note, I also get this sometimes: A preload for 'https://storage.infowisesolutions.com/ufspfx/v1400/infowise-slp.js' is found, but is not used because the request credentials mode does not match. Consider taking a look at crossorigin attribute. I have no idea where it's coming from and why it would suddenly ask for this attribute. It's something on your side.

[vladigubler]

And there is also this now: The resource at “https://storage.infowisesolutions.com/ufspfx/v1400/infowise-design.js” preloaded with link preload was not used within a few seconds. Make sure all attributes of the preload tag are set correctly.
This happens in Firefox.

[vladigubler]

Also, today the issue spread to all lists using the MS Lists interface, please help!

@vladigubler that seems unrelated; please feel free to open a new thread about those.

[vladigubler]

@reedpamsft What do you mean unrelated? these are all related to the SPFx customizer not being loaded. It refuses to loads the JS file, the messages change according to the type of browser. In Edge/Chrome the usual message is usually "is found, but is not used because the request credentials mode does not match. Consider taking a look at crossorigin attribute" or " is found, but is not used due to an unknown reason"

[reedpamsft]

@vladigubler okay, I'm really sorry, I'm getting this mixed up with another issue that came across my inbox... I'll send this to the appropriate folks.

[vladigubler]

@reedpamsft Is there any ETA when it's going to be fixed. According to our customers it stopped working within the last 24 hours on all the lists it previously worked on. I'm guessing an update was recently pushed out?

[natalieethell]

@vladigubler as discussed over mail, I believe this issue should be fixed now. We rolled back a change that caused a regression for this experience.

[Kolyangus]

I wasn't added to the mail correspondence but confirm from my side the issue appears to be resolved based on the roll back. Hopefully it's also solved for @vladigubler

[vladigubler]

Looking good! Was very impressed by the turnaround! I will have more people confirm it tomorrow. Regards, Vladimir Gubler [signatureImage]
