tflint --langserver fails to start, complains about exec format error in google ruleset

[ianchesal]

Summary

Trying to use the language server integration for tflint along with the tflint-ruleset-google ruleset `v0.25.0.

Running the linter, standalone, with this ruleset and configuration works fine. But starting it in LSP mode has it fail with:

> /Users/ianchesal/.local/share/nvim/mason/bin/tflint --langserver
15:27:50 langserver.go:28: Starting language server...
15:27:50 langserver.go:32: Failed to start language server: fork/exec .tflint.d/plugins/github.com/terraform-linters/tflint-ruleset-google/0.25.0/tflint-ruleset-google: exec format error

I'm using tflin version:

> /Users/ianchesal/.local/share/nvim/mason/bin/tflint --version
TFLint version 0.48.0

And it's been installed via Mason in my NeoVIM environment. Mason is starting the server like so:

 Config: tflint
 	filetypes:         terraform
 	root directory:    /Users/ianchesal/src/infrastructure
 	cmd:               /Users/ianchesal/.local/share/nvim/mason/bin/tflint --langserver
 	cmd is executable: true
 	autostart:         true
 	custom handlers:   

Note: if I get rid of of my.tflint.hcl file, the LSP mode works as expected.

Command

tflint --langserver

Terraform Configuration

N/A -- the server doesn't even start up so there's no Terraform being scanned

TFLint Configuration

config {
  plugin_dir = "./.tflint.d/plugins"
}

plugin "google" {
  enabled = true
  version = "0.25.0"
  source  = "github.com/terraform-linters/tflint-ruleset-google"
}

Output

And suddenly it's fine. I have no idea why.

[bendrucker]

"Exec format error" typically refers to an executable that is malformed for the system where you're trying to run it. The most common cause is attempting to run an executable compiled for a different OS or architecture. The fact that you're overriding plugin_dir and didn't include tflint --init in your repro steps makes me suspicious that you had a Linux version of the plugin already installed.

[ianchesal]

Ah! Yes. That's exactly it. The --init was done from a containered version of tflint and not the macOS version that Mason installed.
