Onboarding issue in production

We tried to onboard a device in production, but we are getting error on onboarding

link = “https://gw-fatoora.zatca.gov.sa/e-invoicing/developer-portal

endpoint = ‘/compliance/invoices’

when calling this section of api its returning

{‘validationResults’: {‘infoMessages’: [{‘type’: ‘INFO’, ‘code’: ‘XSD_ZATCA_VALID’, ‘category’: ‘XSD validation’, ‘message’: ‘Complied with UBL 2.1 standards in line with ZATCA specifications’, ‘status’: ‘PASS’}], ‘warningMessages’: [{‘type’: ‘WARNING’, ‘code’: ‘invalid-signing-certificate’, ‘category’: ‘CERTIFICATE_ERRORS’, ‘message’: ‘X509Certificate (CCSID / PCSID) used for signing is not valid certificate (CCSID / PCSID) for this VAT Registration Number.’, ‘status’: ‘WARNING’}], ‘errorMessages’: , ‘status’: ‘WARNING’}, ‘reportingStatus’: ‘REPORTED’, ‘clearanceStatus’: None, ‘qrSellertStatus’: None, ‘qrBuyertStatus’: None}
