Clarification on CSR Serial Number Character Limit

Hi ZATCA Support Team,

Yesterday we encountered the following error while registering a new EGS:

{
  "type": "ERROR",
  "message": "The provided Certificate Signing Request (CSR) is invalid. Maximum number of characters for Serial Number should be less than or equal to 64.",
  "category": "CSR_VALIDATION",
  "code": "EXCEED_CHARACTER_LIMIT",
  "status": "ERROR"
}

We did not make any changes on our side, and we have previously registered EGSs successfully using serial numbers of the same length. Additionally, the current documentation does not mention a 64-character limit for the serial number.

Could you please confirm whether this is a newly introduced validation rule that we should follow going forward, or if this validation was applied in error?

Thank you for your support.
