CTI Problem - Problems with direction

Hi,

we try to add an 3CX Call Flow to send to Zammad CTI Agent:
X-Frame-Options: SAMEORIGIN
X-XSS-Protection: 1; mode=block
X-Content-Type-Options: nosniff
X-Download-Options: noopen
X-Permitted-Cross-Domain-Policies: none
Referrer-Policy: strict-origin-when-cross-origin
Content-Type: application/json; charset=utf-8
{“error”:“Invalid ‘direction’!”}

Anyone here have seen that error?

The Direction is set correctly.

Thanks!
