Unfortunately, you do have to go through them and check them all. However, chances are it's one of the ones being used on the card that was mentioned so I'd start there.

Hey! Looks like there's some invalid beast modes on the cards that are referenced in the error message. You should be able to go to the card ID referenced and find a beast mode that's referencing "City", "ID" Etc. The root problem likely does not have to do with the time zone changes you've made. Happy to help troubleshoot…

Edit: I missed the part where you already tried the list endpoint. There are some undocumented endpoints you can use to search for a dataset by name. You could ask your CSM if they can get a resource to help with finding the best endpoints to use

I've had similar issues with this. I'd post it to the idea board: https://dojo.domo.com/main/categories/ideas

You could set a Default Filter view to default the year filter to FY23 and then set up your slicer card to override that filter.

Connectors do not work with MFA unfortunately. Most APIs have alternate methods to authenticate. In this case, Trade Desk has short term and long term API tokens. Domo is using the short term. You could work with your CSM/AE to see how hard it would be to ask Domo to allow you to authenticate with a long term token instead…
