Thank you for your response.
It seems that the error occurred because we were running on a dummy domain created for testing purposes.
When we ran it on a legitimate domain, it worked fine.
I should have checked more.
Thank you very much.

I solved the problem, but after the url.
/?doing_wp_cron=1696312—
string after the url.
Is there any way to work around this?
