This upgrades hcl2 library dependency to pick up
hashicorp/hcl2#113 .
Prior to this change, parsing and decoding array attributes containing
invalid errors (e.g. references to unknown variables) are silently
dropped, with
cty.Unknown
being assigned to the bad element.Rather than showing a type/meaningful error from hcl2, we get a very cryptic error message from msgpack layer trying to handle
cty.unknown
. Sometimes, we do get an hcl type validation error back, but it's still cryptic e.g.Incorrect attribute value type; Inappropriate value for attribute "list_field": map of string required
without explaining why it's inappropriate.This ensures that we propagate diagnostics correctly and report
meaningful errors to users.
The tests capture the behavior, you can see the failing tests in https://travis-ci.org/hashicorp/nomad/jobs/546843716 and they pass in the latest commit of this PR: https://travis-ci.org/hashicorp/nomad/jobs/546848034 .
