Users.GetSettingsAsync throws a region enumeration error

[michael-aj-kennedy]

We have some code which iterates through a list of users and retrieves a list of settings for each user by calling client.Users.GetSettingsAsync(user.Id).

This code is throwing the following error:

System.ArgumentException: There is no value in the DataCenterRegion enum that corresponds to 'TW'.

We've been using ZoomNet v0.51.1 for a while & haven't seen any problems with this function, implying that Zoom have changed something which has had a knock-on effect here. Upgraded to 0.57 and still experiencing the same error.

We've tested against multiple users & are experiencing the same error for each of them (none of whom are setup with what I assume is the Taiwanese region).

ZoomNet contains a short list of 14 date center regions such as United Sates, Canada, Europe, etc. which I derived from the documentation for the data_center_regions field. Sounds like Zoom added a bunch of regions (42 to be exact) on January 9 2023 based on the "last modified" date here. I need to incorporate these additional data center regions to the DataCenterRegion enumeration in ZoomNet.

However, I'm confused by the fact that I don't see TW on this list of additional regions???

[Jericho]

Fun fact: Tokyo is present in the original list of 14 data center region and it's duplicated in the list of additional regions. This means that there are 41 additional regions, not 42.

I added all the new regions, also added TW and published a beta for you to try. I am confident it will solve the problem for users configured in the Taiwanese region. Let me know if it indeed solves the problem and I will publish to NuGet.

Hi @Jericho

Well it's better than it was... I'm getting the same error, but this time for the CH region, which also doesn't appear in Zoom's list of region codes!

System.ArgumentException: There is no value in the DataCenterRegion enum that corresponds to 'CH'.

I've done some additional testing using our code and a modified version of the ZoomNet codebase. It's looking like the only missing properties are TW (presumably Taiwan) and CH (which I thought was a duplicate of China, but google suggests represents Switzerland).

If I add both of these to DataCenterRegion then the error goes away.

[Jericho]

Added Switzerland and I am in the process of publishing 0.58.0 to NuGet. Should be publicly available in the next 30 minutes or so.

Fingers crossed: I hope we don't find any more "undocumented" regions!

:tada: This issue has been resolved in version 0.58.0 :tada:

The release is available on:

Works perfectly. Thanks for getting that done so quickly!
