Intermittent Issue: continuously (in regular intervals) Getting 500 Error from ZATCA (very frequently) last few days

Since 24/11 afternoon, we are continuously (in regular) facing 500 error response from ZATCA, while submitting invoices to ZATCA.
Anyone else experiencing the same issue?

@Ankit.K.Tiwari Could you please check and suggest from your end! Thanks in advance!
