Redis elasticache Global datastore

We have created primary and secondary cluster in 2 AWS regions and also one Global datastore with both clusters. Now when we are trying to increase replica in secondary cluster getting below error :
I am using Terraform v0.11.15 and AWS provider 4.18.0 version
Let me know if anyone can help me on this.
