Timezone came null

Description
We had subscribed zoom events.
Recently we observed that timezone starts coming null in some zoom events while it is coming fine at same time in other events.
Due to which request validation got broke.

Invalid Request - Timezone is null

Hi @ucliveengg,

Thanks for reaching out about this—I noticed that this appears to be for your Personal Meeting ID (PMI). Are you only seeing this null for meetings using your PMI, or other non-PMI meetings as well?

Thanks,
Will

hi @will.zoom ,
Can you reproduce this scenario and check at your end if this is being null for PMI or non PMI?

Hi @ucliveengg,

I do not see this issue for non-PMI meetings.

Thanks!
Will
