Error fetching vpcUUID from network cidr=%s

Error message

Error fetching vpcUUID from network cidr=%s

What it means

Wraps/report GetVPCUUID failure in the DO LB renderer: the VPC UUID could not be resolved from the configured network CIDR. Note the underlying error is not chained — only the CIDR is reported, which loses the root cause.

Solutions

1. Verify the network CIDR corresponds to an existing DO VPC
2. Check the VPC name configuration
3. Re-run the render after correcting VPC settings
