initializationOptions: Cannot read property 'config' of undefined

[last-partizan]

Hi, i'm trying to use vue-language-server with vim and LanguageClient-neovim and it does not work.

I traced bug to this error:

00:54:01 WARN unnamed src/language_server_protocol.rs:2132 Failed to start language server automatically. Error: Failure { jsonrpc: Some(V2), error: Error { code: InternalError, message: "Request initialize failed with message: Cannot read property \'config\' of undefined", data: None }, id: Num(1) }

https://github.com/autozimu/LanguageClient-neovim/blob/next/src/language_server_protocol.rs#L897

Looks like initializationOptions can be null, but vue-language-server does not take this into account here:

vetur/server/src/services/vls.ts

Line 83 in 82d1603

logger.setLevel(_.get(params.initializationOptions.config, ['vetur', 'dev', 'logLevel'], 'INFO'));

It looks like trivial issue, can you fix it or should i make pull-request?

In my (unsuccessful) attempts to use VLS in atom, I have gotten rid of the errors by moving config into the path array.

It clears up the errors, but I am still not getting messages from the language server in atom.

-  logger.setLevel(_.get(params.initializationOptions.config, ['vetur', 'dev', 'logLevel'], 'INFO')); 
+  logger.setLevel(_.get(params.initializationOptions, ['config', 'vetur', 'dev', 'logLevel'], 'INFO'));

Any workaround?

Isn't this already fixed?

No, without my patch I still see same error.

Fixed by #1705.
