Notification Center error post-update, two updates listed (one seemingly obsolete)

English General
1

Since updating Notification Center last night, all three of my NASs (TS-231K, TS-328 and TS-453Be) display the following error upon application launch:

“Unknown error occurred due to invalid operation or lack of required information.”

They also stopped generating notifications until after I rebooted them this morning. They’re all running the latest available firmware, which I also installed this morning in attempting to resolve the Notification Center error.

Going here:

I see two different “latest” versions of Notification Center listed, both with the same July 30 release date:

  • v1.9.2.3139, which is what all three systems now have installed, and which seems to be obsolete per the version number, and
  • v2.1.0.3389, which from the recent-versions cadence I assume is actually the latest version

I’m guessing that the fact that I’m being served up an obsolete version of Notification Center for update/installation is the root cause of the error. QNAP, can you please fix this and/or otherwise respond with ideas asap?

Hello,

I have the same error message on a TS-253A.
Latest firmware (updated today), Notification Center 1.9.2.3139 installed.

Apologies for the problem you’ve encountered. We have confirmed this issue, and our technical team is currently working on a fix.

Regarding the two versions you saw in the release notes, this is because we provide them for use with different firmware versions.

We apologize again for the issue and will handle it.

Thanks, @SteveKo. What should we do for now? I’d suggest uninstalling it and then installing again, which “should” access the previous valid version, but although the new flawed version has now been pulled from the revision history:

It’s still available for download, so I suspect I’d just get it again if I went this route:

Note that my three NASs have unique Notification Center “build” versions; “arm_al” (the TS-231K), “arm_64” (the TS-328) and “x86_64” (the TS-453Be).

Thanks in advance for your ongoing guidance on this issue.

Minor correction: the TS-231K is “arm_al” (in uppercase, this is ARM_AL), not “arm_ai”. :nerd_face:

Thanks, @OneCD, correction made to my prior post!

@SteveKo, six days later and still no update. Status, please?

Apologies for the late reply.

You can resolve this by reinstalling the previous version of Notification Center using this FAQ: Notification Center displays “An unknown error occurred due to an invalid operation or lack of required information.” | QNAP

Please note that you do not need to remove the current version before reinstalling.

We expect a new, fixed version to be released soon. Thanks for your understanding!

@SteveKo, thanks. However, when I do this I’m being offered v1.9.2.3110, dated May 16. It would seem that I should instead be offered v2.1.0.3356, dated July 16 (and the version that had been installed prior to this recent issue). Thoughts?

My apologies for the confusion. Just to clarify, Notification Center v2.1.x is currently only for QuTS hero 5.3, while Notification Center v1.9.x is for versions prior to 5.2.

I’ll report this to our internal team and we will evaluate how to improve our announcement information in the future. Thanks!

@SteveKo, thank you. I’d gone ahead and successfully downgraded all three NASs last night before bed…and of course woke up this morning to find the fixed updated version of Notification Center now available :joy: (I upgraded all three NASs and they’re fine)
