LSP failed to handle notification - Sequence contains more than one matching element #1403

I encounter the same issue. I haven't yet been able to resolve it as the error originates in the https://github.com/OmniSharp/csharp-language-server-protocol project. No .pdb's exist so I have to manually download, compile, integrate the .dll, and debug, and I haven't had enough time to do that yet. |
Same issue here. I guess that the client sends a capability that's not well understood by OmniSharp, and the tricky part is to find out which one it is. {"jsonrpc":"2.0","id":"1","method":"initialize","params":{"processId":28133,"rootPath":"/home/mistria/runtime-New_configuration(2)/fd/","rootUri":"file:///home/mistria/runtime-New_configuration(2)/fd/","capabilities":{"workspace":{"applyEdit":true,"workspaceEdit":{"documentChanges":true,"resourceOperations":["create","delete","rename"],"failureHandling":"undo"},"symbol":{},"executeCommand":{"dynamicRegistration":true},"workspaceFolders":true},"textDocument":{"synchronization":{"willSave":true,"willSaveWaitUntil":true,"didSave":true},"completion":{"completionItem":{"snippetSupport":true}},"hover":{},"signatureHelp":{},"references":{},"documentHighlight":{},"documentSymbol":{"symbolKind":{"valueSet":[18,17,5,14,9,10,22,24,8,1,12,11,20,6,2,3,21,16,19,25,4,7,15,23,26,13]},"hierarchicalDocumentSymbolSupport":true},"formatting":{},"rangeFormatting":{},"definition":{},"codeAction":{"codeActionLiteralSupport":{"codeActionKind":{"valueSet":["quickfix","refactor","refactor.extract","refactor.inline","refactor.rewrite","source","source.organizeImports"]}},"dynamicRegistration":true},"codeLens":{},"documentLink":{},"colorProvider":{},"rename":{}}},"clientName":"Eclipse Platform","trace":"off"}} |
I tweaked my client to sort out which capabilities do cause an issue with OmniSharp, from the previous message, Omnisharp will fail whenever |
This is where it is exploding. The SynchronizationCapability has 6 different interfaces attached to it, and all 6 of them satisfy the conditions of .Single(), which makes the code explode. I'm not entirely sure how to fix this yet. I mean, you could probably just change .Single() to .First() and hope for the best. |
Ah, changing to .First() just moves the error someplace else. |
I am also running into this problem with vim-ale. These are the capabilities that vim-ale is sending to omnisharp-roslyn's LSP server: https://github.com/w0rp/ale/blob/master/autoload/ale/lsp.vim#L327-L385 Removing the |
Looks like this was solved on OmniSharp/csharp-language-server-protocol#132. @mholo65, maybe we have to upgrade something? |
- Fixes OmniSharp#1403
@luizribeiro sent PR for updating LSP libs in #1503 |
I just tried the PR and after months of LSP being broken, it works again! Thank you very much for fixing it! |
I get the following error when attempting to start the server in with -lsp. I have built from the latest commit on master.
