Language server uses an ambiguous provider version when multiple .terraform environments exist

[seanhoughton]

Language Server Version

v0.32.8

Terraform Version

Terraform v1.7.3 on darwin_arm64

Client Version

VSCode 1.87.2

Terraform Configuration

terraform {
  required_providers {
    azuread = {
      source  = "hashicorp/azuread"
      version = "~> 2.47.0"
    }
  }
}

data "azuread_application_published_app_ids" "well_known" {}

Steps to Reproduce

1. Install multiple versions of a terraform provider
2. Hover over a resource title
3. Observe the incorrect version of the provider being used

Alternatively, just hover over the provider to see the incorrect version number

Expected Behavior

The language server should use the version of the provider set in the .terraform.lock.hcl or consider version constraints in the required_providers block.

Actual Behavior

The language server appears to pick a consistent (but sometimes incorrect) version from the ones that are installed.

Gist

No response

Workarounds

Delete all old versions of the provider from the .terraform/providers folder

Hi @seanhoughton,

Thanks for the report! I think I need more details to reproduce the problem.
Can you please share your lockfile and the contents of your .terraform/providers directory?

I assume you ended up with multiple versions of the same provider through upgrades? Internally, the language server uses terraform provider schemas -json to get the schema for an installed provider. So we partially rely on Terraform to give us the correct schema, but we also parse the lockfile and configuration constraints. We use this information to pick the most appropriate schema version, either from disk or from our bundled schema.

[seanhoughton]

I just reproduced it again with only a single provider version installed in the plugins folder. It's a mystery where this provider is coming from. I've combed through the language server logs and can't find anything that shows where the provider plugins are coming from.

Here's the lockfile

}

The schema looks correct. I've isolated the azuread_application_password resource because the schema is pretty big, and this highlights the problem. The application_object_id field was deprecated in a recent update of the azuread provider and exists in the schema output with "deprecated: true".

Thanks for the additional details!

We have two sources for provider schemas:

• We bundle the latest version of the provider schema at language server build time to provide a good out-of-the-box experience
• We get the schema from locally installed providers via terraform providers schema -json

The latter should always be preferred over the bundled one, as it is a better match to the provider version in use.

The language server build 0.32.8 shipped with azuread 2.47.0, so I'm also confused where 2.41.0 came from. Can you double check your language server version? It is listed at the top of the log output:

Launching language server: /Users/dbanck/Projects/terraform-ls/terraform-ls serve
Client: Stopped --> Starting
2024/03/19 14:21:09 serve_command.go:108: Starting terraform-ls 0.32.8
2024/03/19 14:21:09 service.go:105: Preparing new session ...

Are there other .terraform directories in your workspace (the root folder you opened in VS Code) with a different azuread version?

[seanhoughton]

I'm using the 32.8 language server, but I think I figured it out. I'm using three different environments in the project. All of the environments share a set of modules but each have their own .terraform state. The error I'm seeing is only when I'm in a file in the /modules folder which has an ambiguous provider version if the prod and staging environments use different provider configurations. I had originally suspected this and updated two environments but I just noticed that there's a third one in there which uses 2.41.0 instead of 2.47.0 - so that solves the mystery of where 2.41.0 came from.

I'm not sure what the fix should be. It could be a workspace configuration setting similar to the "select the python virtual environment" option in the Python extension. Ultimately all the environments should be on the same version so I have resolved this by ensuring all environments are on the same provider revisions.

I am experiencing this issue and my situation is simpler than @seanhoughton's.

I am using terraform-ls version 0.34.3, with the vercel provider version 1.14.1. I've upgraded this from using ~> 0.4, and terraform-ls is refusing to use the new version. I have completely wiped the .terraform directory and done a reinit, and verified that there is only one .terraform directory and only one correct version of the provider in .terraform/providers/registry.terraform.io/vercel/vercel.

The specific error I'm getting is that the lsp thinks the vercel_project.resource_config attribute is unexpected. Running terraform providers schema -json shows that the attribute is defined in the schema.
Here's the lock file for good measure:
