Fixes issue with Entrust CA on VaaS
Fixes an issue whereby requesting a certificate in VaaS to a Certificate Issuing Template that uses Entrust CA throws an error.
Under some conditions Entrust CA may take too long to issue certificate, which causes VaaS to send 201 Created response with no certifcateIds
. This is expected behavior and requires the sdk to poll for the certificate request until the status is ISSUED
or FAILED
