Unable to get autocomplete working with terraform.

[tdwalton]

I brew installed terraform-ls and terraform-lsp and enabled completion for ALE in my .vimrc and am unable to get code completion working in Terraform. ALEInfo shows Failed to find project root, language server won't start. for both terraform_ls and terraform_lsp. Checkov and tfsec are both running and returning errors/warnings.

I saw another post with someone having a similar problem with another lsp tool, but it was because they hadn't init'd their project and the file the linter was looking for to find the root wasn't there. AFAICT, the terraform linter is looking for a .terraform directory, which exists in my case.

I ran both terraform-ls and terraform-lsp on the cli, and both started successfully, though I'm not sure how to test those tools any further than that.

ALEInfo is attached below. TIA for any insight into how to fix this.

Available Linters: ['checkov', 'terraform', 'terraform_ls', 'terraform_lsp', 'tflint', 'tfsec']
   Linter Aliases:
'terraform_ls' -> ['terraformls']
  Enabled Linters: ['checkov', 'terraform', 'terraform_ls', 'terraform_lsp', 'tflint', 'tfsec']
  Ignored Linters: []
 Suggested Fixers:
  'remove_trailing_lines' - Remove all blank lines at the end of a file.
  'terraform' - Fix tf and hcl files with terraform fmt.
  'trim_whitespace' - Remove all trailing whitespace characters at the end of every line.

Ugh, how embarrassing. "When in doubt, reboot.", applies here, as in many cases.
