This appears to be a design flaw in HCL. ### Actual Behavior - Applying `[*]` to a list causes HCL to try to produce a list. - Applying `[*]` to a scalar value causes HCL to try to produce a zero- or one-element tuple depending on the nullness of the value. - Taken together, the second rule violates an assumption being made by the first: that because all elements of a list have the same type by definition, and because a splat expression applies all of its nested steps equally to all elements of the list, that therefore all inner results should be of the same type. An empty tuple and a one-element tuple have different types, so the outermost splat crashes by asking `cty` to try to construct a list using values of different types: ``` panic: inconsistent list element types (cty.EmptyTuple then cty.Tuple([]cty.Type{cty.String})) goroutine 64 [running]: runtime/debug.Stack() runtime/debug/stack.go:26 +0x5e github.com/hashicorp/terraform/internal/logging.PanicHandler() github.com/hashicorp/terraform/internal/logging/panic.go:84 +0x16a panic({0x31598a0?, 0xc0009b4090?}) runtime/panic.go:785 +0x132 github.com/hashicorp/terraform/internal/terraform.(*Graph).walk.func1.1() github.com/hashicorp/terraform/internal/terraform/graph.go:59 +0x4c5 panic({0x31598a0?, 0xc0009b4090?}) runtime/panic.go:785 +0x132 github.com/zclconf/go-cty/cty.ListVal({0xc0009b1240, 0x2, 0x3e21190?}) github.com/zclconf/go-cty@v1.15.1-0.20241111215639-63279be090d7/cty/value_init.go:165 +0x47b github.com/hashicorp/hcl/v2/hclsyntax.(*SplatExpr).Value(0xc000b30210, 0xc0009a85e8) github.com/hashicorp/hcl/v2@v2.23.0/hclsyntax/expression.go:1941 +0x1730 github.com/hashicorp/terraform/internal/lang.(*Scope).EvalExpr(0xc000708ea0, {0x3e22e08, 0xc000b30210}, {{0x3e21898?, 0x5a441c0?}}) github.com/hashicorp/terraform/internal/lang/eval.go:179 +0x1a5 github.com/hashicorp/terraform/internal/terraform.(*BuiltinEvalContext).EvaluateExpr(0x0?, {0x3e22e08, 0xc000b30210}, {{0x3e21898?, 0x5a441c0?}}, {0x0?, 0x0?}) github.com/hashicorp/terraform/internal/terraform/eval_context_builtin.go:331 +0xab github.com/hashicorp/terraform/internal/terraform.(*NodeApplyableOutput).Execute(0xc0006d8a80, {0x3e48eb8, 0xc0001dad00}, 0x50?) github.com/hashicorp/terraform/internal/terraform/node_output.go:439 +0x6dc github.com/hashicorp/terraform/internal/terraform.(*ContextGraphWalker).Execute(0xc0008a2420, {0x3e48eb8, 0xc0001dad00}, {0x7f9d20c9c308, 0xc0006d8a80}) github.com/hashicorp/terraform/internal/terraform/graph_walk_context.go:161 +0xb5 github.com/hashicorp/terraform/internal/terraform.(*Graph).walk.func1({0x3534740, 0xc0006d8a80}) github.com/hashicorp/terraform/internal/terraform/graph.go:143 +0x7c3 github.com/hashicorp/terraform/internal/dag.(*Walker).walkVertex(0xc000b53980, {0x3534740, 0xc0006d8a80}, 0xc0009a5300) github.com/hashicorp/terraform/internal/dag/walk.go:384 +0x2d1 created by github.com/hashicorp/terraform/internal/dag.(*Walker).Update in goroutine 58 github.com/hashicorp/terraform/internal/dag/walk.go:307 +0xfb3 ``` ### Steps to Reproduce Use the configuration I shared above with `terraform plan`. Terraform should crash as soon as graph traversal reaches the output value named "example". ### Additional Context There is a more complete -- but also significantly more complicated -- example of this problem in https://github.com/opentofu/opentofu/issues/2327, since this problem was originally discovered by an OpenTofu user. I'm opening an issue here only to help with prioritization, as requested in https://github.com/hashicorp/hcl/pull/724. ### References https://github.com/opentofu/opentofu/issues/2327 - original bug report for OpenTofu's version of this bug https://github.com/hashicorp/hcl/issues/723 - HCL bug report based on the OpenTofu bug https://github.com/hashicorp/hcl/pull/724 - My initial attempt to "fix" this by making it return a normal error instead of crashing ### Generative AI / LLM assisted development?
