When trying to create an organization… it turns out that the class is not usable because the API needs an organization id, the id field is private in the class and nothing is setting it.
So, essentially the Organization class and any API that takes it, can’t be use.
I can’t speak to the issues with the C# client, but the troubles you’re having with the UI make it sound like you’re using InfluxDB Cloud 2. If that’s true, you won’t be able to create a 2nd organization under your account. When you created an account, it created an org for you using the email address you provided. Your orgID can be extracted from the UI URL: View organizations in InfluxDB | InfluxDB OSS 2.0 Documentation.
I’m using the OSS version. The only way I could extract the organization Id was through the command line. The description of the UI in the link you sent doesn’t match what I see in the UI itself.
