Unable to Add Panelist via API

API Endpoint(s) and/or Zoom API Event(s)
context.*]

Description
I’m trying to use this API to add panelists to a webinar.
Here is the situation.

If the email doesn’t belong to an account, then it add to the list, however, if it’s a known email account, then it’s not added to the webinar
We use SSO

How To Reproduce
Steps to reproduce the behavior:

JSON =
{
“panelists”: [
{
“email”: “alexandra.xxxxxxx@xxxxxxxxxxx.com”,
“name”: “xxxxxxx, Alexandra”
},
{
“email”: “eloisa.xxxxxxxxx@xxxxxxxxxxx.com”,
“name”: “xxxxxxx, Eloisa”
}
]
}

URL =
https://api.zoom.us/v2/webinars/$($WebinarID)/panelists

Auth =
OAuth

This is similar to:

Here is an execution with unknow email:
{
“panelists”: [
{
“email”: “testalexandra.xxxxxxx@xxxxxxx.com”,
“name”: “testXXXX, Alexandra”
},
{
“email”: “testeloisa.xxxxxxx@xxxxxxx.com”,
“name”: “testXXXX, Eloisa”
}
]
}

Execution from a known email:
{
“panelists”: [
{
“email”: “alexandra.xxxxxxx@xxxxxxx.com”,
“name”: “xxxxxxx, Alexandra”
},
{
“email”: “eloisa.xxxxxxx@xxxxxxx.com”,
“name”: “xxxxxxx, Eloisa”
}
]
}
