Extension give error in VSC - Command "dot" failed. MESSAGE:spawn dot ENOENT

[TinLe]

I opened a .tf file, then Cmd-Shift-p and get the above error. I get a blank Terraform Live Graph pane on the right side of my .tf code in VSC.

I am using Terraform Live Graph v0.0.1

Looks like this extension requires graphviz installed. I've installed graphviz via homebrew on my Macbook and I do not get that error anymore

Fix by:
brew install graphviz

However, the Terraform Live Graph pane is blank. No graphs.

Hi
Can you successfully execute terraform graph in the working directory of your project?

[adamiBs]

After looking into this I can conclude that this is a bug, a dependency of the one of the extension's dependencies is an installation of graphviz. I'll work on fixing the issue and removing dependance on graphviz, and in the meanwhile I'll update the README.md installation instructions.

[TinLe]

Hi Can you successfully execute terraform graph in the working directory of your project?

Yes. That works fine in any of the directory that contains .tf of my repo.

[kevinmccurdybrd]

@adamiBs this is still outstanding for me on a machine with TF 1.4.0 and GraphViz 7.1.0 on WIndows 10 22H2. I can successfully run a TF Graph in the directory with my TF files.

[blckpythn]

Also having this issue. TF 1.4, GraphViz 7.1.
terraform graph runs fine.

[adamiBs]

Hi @blckpythn,
I'll look into this. It's quite hard to debug according to the error message. I've created and issue that includes improving error logging for the command execution: #6.
BTW, #6 is a good first issue =).

[adamiBs]

Also having this issue. TF 1.4, GraphViz 7.1. terraform graph runs fine.

Could you please provide the OS information of where your vscode is running?

Hello @adamiBs . Thank you for making such a cool extension! Unfortunately I'm having similar issues as those above mentioned. I figured I'd post my issue/setup in case it helps others troubleshoot too.

Issue #1	Create a report to help us improve	[BUG]: vscode-terraform-live-graph	graph doesn't populate

Describe the bug While `terraform graph` works just fine in CLI, the extension Terraform Live Graph doesn't work. I got a similar message as the one [above](https://github.com//issues/1#issue-1620267017) about cmd dot failing. .

To Reproduce Steps to reproduce the behavior:

1. Open VSC
2. Click on any .tf file (formatted & validatedby terraform itself via `terraform fmt -recursive` and `terraform validate`)
3. Then open the cmd pallete and use Terraform Live Graph extension
4. The graph doesn't populate but `terraform graph` does work

Expected behavior For the extension to successfully graph my infrastructure as `terraform graph` does

Screenshots  Looking at the 3 columns (left to right), you can see that I have .tf files open. I also opened the live graph extension via the cmd pallete. And to confirm files are valid/TF is working fine, `terraform graph` output is shown in last column

Versions (please complete the following information):

• OS: [Linux Mint 20.3 x86_64]
• VSCode Version: [1.76.1]
• Terraform Live Graph Extension for VSCode Version [v0.0.2]
• Terraform Version: [v1.4.0]

Additional context I've restarted Code, my computer, and have ensured that graphviz is installed on my machine (2.42.2-3build2). I've also tried a different Terraform codebase and nothing was still graphed (via the extension).

Hi @crc8109 & @TinLe,
Could you please post the Extension Host log?
It's reachable through the Command Palette (CMD+Shift+P / Ctrl+Shift+P): Select "Developer: Show Logs..." and then "Extension Host".
This should open a window with additional context, usually.

[blckpythn]

Is this what you're looking for?

[adamiBs]

Exactly 😁.
I think that a fix I’ve implemented in the newest version for this issue #2. Should resolve this. Please check by using the latest version.

[blckpythn]

Same issue with .0.0.4 unfortunately :(

[adamiBs]

I’ll look into it, thanks for the quick response.

[blckpythn]

Does the extension try to run terraform graph in the system context?
My user environment PATH has terraform and graphviz entries, but system does not.

Hello @adamiBs . Here's the output related to the extension:

[adamiBs]

I've done the following in v0.0.5:

1. Improved error logging to hopefully find the root cause of the issue (if it still exists), and future issues.
2. I've changes the implementation of spawning dot commands from the graphviz library.

Please check version v0.0.5 and update on any new information.

[blckpythn]

Not much different, except less error info.

[adamiBs]

Ok, it seems unrelated specifically to execution of dot commands. Maybe your initial assumption is correct - maybe the extension is running in a different context than your user's context 🤔. Are you initializing VS Code 'as administrator'? If so, I assume the program's context is effected.

Do terraform commands work from the VS Code terminal?

[blckpythn]

Terraform commands do work, whether I run as administrator or not.
I get the same behavior from the extension running normally or as admin, though I'm usually running as admin.

The right pane for Terraform Live Graph has a single square white dot at the top.

[Lito-Frito]

Thanks for trying to patch this so quickly @adamiBs ! I installed the update and ran the same cmds as before. Here's the output:

Please lmk if there's anything else I can do to help

@TinLe

The right pane for Terraform Live Graph has a single square white dot at the top.

It seems as if the extension has loaded correctly. And the small white square is a "correct" state, an immediate workaround would be to reload the extension in a working project.

I will create a new bug to track the issue you've described. #15

[gokhanboranalp]

Check this. If your state is not local. Another rabbit hole.
