I am able to import some accounts without issue. There are some in my AWS Organization though that come up with the generic error:
"Something went wrong when creating one or more data sources"
Is there any way to see more information about what went wrong or suggestions about what different approaches I can take.
I am using a cross-account role. It has been deployed in a consistent IaC way across all accounts so no issue with permissions / naming that I can see - other accounts work fine.
The error usually takes about 15 - 20 minutes to appear.
