GLSP V2.3 - VS-Code Integration - Unknown parameter structure auto

[rsoika]

I am just upgrading from glsp version 2.1 to 2.3. Theia Integration works fine now.
But trying to upgrade my vs-code integration I run into a strange error.
When I start the extension with a vs-code launch configuration:

    {
      "name": "Open-BPMN VS-Code Extension (without Server)",
      "type": "extensionHost",
      "request": "launch",
      "runtimeExecutable": "${execPath}",
      "args": [
        "${workspaceFolder}/workspace",
        "--extensionDevelopmentPath=${workspaceFolder}/extension"
      ],
      "outFiles": [
        "${workspaceFolder}/extension/lib/*.js",
        "${workspaceFolder}/vscode-integration/lib/**/*.js"
      ],
      "sourceMaps": true,
      "env": {
        "GLSP_SERVER_DEBUG": "true",
        "GLSP_SERVER_PORT": "5007"
      }
    }

I see the following javascript error in the web console:

console.ts:137 [Extension Host] rejected promise not handled within 1 second: Error: Unknown parameter structure auto (at console.<anonymous> (file:///usr/share/code/resources/app/out/vs/workbench/api/node/extensionHostProcess.js:174:26810))

I can't really location the source of this error messages.

I am running this with an external stared java sever. And I can see that the client seems to connect to the server:

2025-02-14 14:33:29,696624000 [DefaultActionDispatcher 4] INFO  DefaultActionDispatcher - Terminating DefaultActionDispatcher thread DefaultActionDispatcher 4

But the editor plane is empty and no modler plane is loaded.

Hi @rsoika,

if I'm not mistaken this error occurs if two different versions of vscode-jsonrpc are resolved. (see also #1182).

In theory all GLSP components depend on the same fixed version of vscode-jsonrpc (8.2.0) but it seems like we overlooked to adapt the dependency of @eclipse-glsp/vsocde-integration accordingly

It is set to ^8.0.2 wich means it will resolve to the latest 8.x version. At the point of the 2.3 release this version was 8.2.0 that's why everything worked back then. In the meantime a new version got released which means every vscode-integration based project might run into this issue.

If have opened #1481 to track this.

Until a fix is available you can use yarn resolutions to fix the version.

Just add the following to your root package.json:

"resolutions": {
    "**/vscode-jsonrpc": "8.2.0"
  }

After rebuilding you can verify that everything worked correctly with yarn why vscode-jsonrpc. This should only find one version (8.2.0)

Yes you were right! Setting the "**/vscode-jsonrpc": "8.2.0" into the resolutions section solved this problem!
Thanks a lot!!
