Webhook notifications seem not to work occasionally

Hi, folks! I’ve been experiencing a problem as title for about 3 weeks. I’ve assigned functions to notification endpoints of Participant/Host joined/left meeting. I’ve been missing those notifications occasionally like this:

  • joined notification of a participant is sent but left one of the same participant is missing
  • left notification of a participant is sent but joined one of the same participant is missing
  • other participants are not affected, both notifications are sent

I made sure that Firewall/VPN of my application are not concerned. I have no idea why suddenly this problem happened and I can’t find how to reproduce.

Could you suggest anything? Thanks in advance.
