We are deploying VMware PKS on VCF and the PKS deployment in PCF Ops Manager completes successfully except in the SDDC Manager it is failing with the below error.
Hence the pks deployment on a VI workload domain is not getting completed.
Please let me know if anyone has faced this issue before or where exactly could be the issue for me to proceed further.
That's too generic of an error message to even guess what the problem might be. You'd need to take a look at the logs to see what it's trying to do.
