Hi,

Ive been trying to send invites to users to by discussion board via the invites API and i keep running into a 500 internal error.

Any advice.

```plaintext
{
"email": "anitsirc+3@gtechme.com",
"skip_email": false,
"custom_message": "string",
"max_redemptions_allowed": 5,
"group_id": 0,
"group_names": "string",
"expires_at": "controlled by invite_expiry_days site setting"
}

```

I think ‘expires\_at’ is supposed to be a timestamp. If you **omit** the value, then it will use the site setting value. Can you try removing `expires_at` from your call?
