To Reproduce Steps to reproduce the behavior:

1. Pipelines fails while runnning command "fx aggregator generate-cert-request --fqdn " intermittently when thelength of x is more then 64.

Expected behavior Pipeline should not fail because of this error.

Desktop (please complete the following information):

• OS: linux and windows
