Server shut down

[ericdude4]

Fresh install of Zed, added Elixir extension, using recommended settings for Expert:

{
  "languages": {
    "Elixir": {
      "language_servers": [
        "expert",
        "!elixir-ls",
        "!next-ls",
        "!lexical",
        "..."
      ]
    },
    "HEEX": {
      "language_servers": [
        "expert",
        "!elixir-ls",
        "!next-ls",
        "!lexical",
        "..."
      ]
    }
  }
}

Then I get no code completion and the following errors any time it formats on save:

2025-10-30T13:07:51-04:00 WARN  [project::lsp_store] Get definition via expert failed: server shut down

@ericdude4 this issue seems to be related to the expert binary, not the Zed extension: elixir-lang/expert#59

[ericdude4]

@PJUllrich Thanks! At what frequency does Zed download a fresh version of the expert binary? Is there a way to force an update? How can I check which version of the expert binary that the Zed extension is using?

[PJUllrich]

@ericdude4 it looks for a new version every time you restart Zed however until this PR #44 is merged, it will never update expert since it always has the same version nightly. Until the PR is merged, you can manually delete the expert version in your Zed folder under extensions/work/elixir/expert. See here to find the Zed folder on your system: https://zed.dev/docs/configuring-zed#auto-install-extensions

Hey @PJUllrich ,

thank you for your grand help. Do you know by any chance what to do next?

1. removed the whole elixir language extension folder
2. Restarted ZED
3. Activated extension (expert downloaded)

Getting the following:

Language server expert:

initializing server expert, id 37: Server reset the connection

@jk-lamb I'm no expert on Expert (😉) but this could be caused by the missing --stdio argument. Until the PR mentioned above is merged and released, could you try this workaround please?

@PJUllrich thank you so much! I have been looking for it for days! You made my day!

[jk-lamb]

Aj guys, now it downloads and great, but have contant "Building engine for " :(

Is it related to same issue?

[PJUllrich]

@jk-lamb generally if Expert gets successfully downloaded and starts, this extension has done its job correctly and any error occurring after that are the responsibility of Expert, not this extension, and should be raised in the Expert repo.

In your case, try deleting the .expert folder in your project. That might help. If not, please create an issue in Expert

[jk-lamb]

Thank you very much @PJUllrich for another tip. Indeed it worked! Expert processed everything.

Thank you again!

[PJUllrich]

@jk-lamb glad to hear it :) Could I ask you to close this issue then since it's a nofix, at least for this repo? I don't have maintainer rights, so can't close it for you.
