Sorry, I cannot help you these days. It would require me to setup the environment and to dig into a documentation I haven't went through in months.

But it seems like an API restriction. I would suggest you to debug/inspect the response object 🐞

By the way: it might be a good idea to use Markdown to format your code snippets 🎨 That makes it easier for other people to help you.

Cheers!

🤔 Interesting. Did you checked if it was because of that user's privacy settings?

Hey. It can be whatever you want. Just like a password, make sure it's a strong one!

Hey! I ran the snippets once again and they still work as expected. Maybe check that you are actually authenticating the client.
