Error: Process completed with exit code 1.Sample Terraform Configuration
Click to expand configuration
resource "aws_dynamodb_table" "test" {
name = "test"
billing_mode = "PAY_PER_REQUEST"
hash_key = "hash"
attribute {
name = "hash"
type = "S"
}
lifecycle {
ignore_changes = [
global_secondary_index,
read_capacity,
write_capacity,

for_each = ["test"]
content {
hash_key = "hash"
name = "name"
projection_type = "ALL"
}
}
}Steps to Reproduce
- Apply configuration to create AWS DynamoDB table
- Rerun plan step which will fail immediately with error:
Error: all indexes must match a defined attribute. Unmatched indexes: [""]
Only affects when global_secondary_index is in lifecycle ignore changes section. It is not affecting plan when changes are not ignored.
