Panic Output

Expected Behavior

Actual Behavior

Intermittent errors:
Error downloading the cluster config [c2skm3gd0nm0nnpu9uj0]: Could not login to openshift account runtime error: slice bounds out of range [8:0]

Re-running a few times the command get past this - it does seem to be some race condition?

Steps to Reproduce

1. terraform apply

Important Factoids

VPC OpenShift clusters. Reproducable on various machines.

experiencing same issue doing terraform plan, apply or destroy, re-running one or twice usually fixes it like @vburckhardt says, but it is becoming really persistent lately.

I am running Terraform v1.0.0 and provider registry.terraform.io/ibm-cloud/ibm v1.26.2

I think this is some kind of intermittent or race condition where the master url of the cluster is not reachable...
We are planning to add some retries on such race condition...
This is PR which is in development to handle retries
#2774

We are planning to make this fix available in next release planned in couple of days(v1.27.0)
