vault_approle_auth_backend_role does not work with vault v1.20

[kinghrothgar]

Attempting to apply simple vault_approle_auth_backend_role consistantly fails and regularly causes panic.

Similarly importing a simple approle role causes failure and panic

Terraform Version

Terraform v0.12.6
provider.vault v2.1.0
vault v1.20

Affected Resource(s)

• vault_approle_auth_backend_role

Terraform Configuration Files

  depends_on = [
    "vault_policy.staging_grpc_ssl_example"
    ,"vault_auth_backend.approle_production"
  ]
  backend            = "${vault_auth_backend.approle_staging.path}"
  role_name          = "grpc_ssl_example"
  policies           = ["staging_grpc_ssl_example"]
}

Debug Output

Output of running terraform apply https://gist.github.com/kinghrothgar/7e52a1c26a78c4d1a86576d41a9c3814

Panic Output

crash.log from import https://gist.github.com/kinghrothgar/ee400f0d2212c4914c9e3878d340a103
crash.log from apply https://gist.github.com/kinghrothgar/a5a246d5c4e3145e50efcd541c209ce8

Steps to Reproduce

1. Create a tf with vault_approle_auth_backend_role
2. terraform apply

[kinghrothgar]

I just tested my terraform files on v1.1.5 and it works. There are approle changes mentioned in v1.2.0 changelog so I assume that's what broke this / the GRPC spec

Should have been fixed by #478

You might want to try ti again with a build from master branch or wait for the next release.

This is fixed in v2.0.0
