Webhook notification BigPanda status 201 but failed notification in checkmk

CMK version:
Raw 2.2.0p8
OS version:
Ubuntu 22.x

Error message:
201: Created Failed to send notification. – Response: {“status”:201,“data”:{}} – 201: Created

Detail:

sending notifications via webhook to bigpanda - alert is recieved by bigpanda - in checkmk we see failed notification with the response 201:created - using Slack and Teams webhook - both same issue - can the 201 response marked as a success not a failed one?
Thx

Quick and dirty fix - would be great, if CheckMK team would add 201 responses in the code - thx

if 200 <= status_code <=201:
    #if status_code == success_code:
        sys.stderr.write(summary)
