Linux getting "CompletionService: Could not find document for file" in LSP mode

[shashank-sharma]

I am using release 1.38.2 - omnisharp-linux-x64-net6.0.tar.gz lsp server command: dotnet [ '/lsp-server/omnisharp/OmniSharp.dll', '-lsp' ]

If I try to pass any input to the LSP server, I get this error: "OmniSharp.Roslyn.CSharp.Services.Completion.CompletionService: Could not find document for file /13764770-cc63-11ec-aaac-b3713373339b/file.cs | 0='/13764770-cc63-11ec-aaac-b3713373339b/file.cs'"

And if I check the path of file.cs file which is created, then it's present at exact same directory. Can anyone help me with what might be wrong with the LSP server ? (Tested using Monaco editor)

This is not specific to net6.0, happens with mono as well (Given codebase is same, it's a different issue), so is there any configuration which I might be missing ?

You need to have a project file available, since files are added to the workspace through projects.

@filipw I have project file as:

total 16
drwxr-xr-x 3 root root 4096 May  5 11:04 .
drwxr-xr-x 1 root root 4096 May  5 11:04 ..
-rw-r--r-- 1 root root  239 May  5 11:04 file.csproj
-rw-r--r-- 1 root root    0 May  5 11:04 file.cs
drwxr-xr-x 2 root root 4096 May  5 11:04 obj

And even get some logs as:

    MsBuildProject: {

    }
  }

      Configuration: 'Debug',
      Platform: 'AnyCPU',
      IsExe: true,
      IsUnityProject: false
    }
  }
}

I made sure that file.csproj is present and dotnet restore happens. Is there something else which is wrong here ?

Any update on this?

@filipw can you please check the filestructure and confirm if anything is missing out? cc/ @shashank-sharma
