Thank you for adhering to this process! It ensures your issue is resolved

Issue Details

Provide a clear description of the problem, including the following key
questions:

What did you do?

Opened a javascript file in vim.

Include description of a minimal test case, including any actual code required
to reproduce the issue.

What did you expect to happen?

Completion functionality in the JS file would be available. I am setting up javascript completion for the first time but have completion running successfully in other languages. I have run the install script using the '--ts-completer' flag and have node/npm installed. Please note that I used nvm to install node; if this is not supported please let me know.

What actually happened?

Completion was not available and the message "RuntimeError: TSServer is not running." was shown.

Can you get the tsserver log file too? It looks like it’s not starting.

Thanks for looking - I did include it in the gist, although it is completely empty.
(this is the file named '/tmp/tsserver_do2f30bo.log' in the gist - if you were referring to a different one please let me know.)

bstaletic · 2019-06-25T18:05:23Z

From the ycmd stderr log:

RuntimeError: Missing 'Content-Length' header

@peterdutton Can you try executing /path/to/YouCompleteMe/third_party/ycmd/third_party/tsserver/bin/tsserver

It should start the TSServer and the first message should be something like:

Content-Length: 76

{"seq":0,"type":"event","event":"typingsInstallerPid","body":{"pid":10267}}

After which, you can try feeding it some garbage like awsedrf followed by enter and TSServer should respond with something like this:

Content-Length: 978

{"seq":0,"type":"response","command":"unknown","request_seq":0,"success":false,"message":"Error processing request. Unexpected token a in JSON at position 0\nSyntaxError: Unexpected token a in JSON at position 0\n    at JSON.parse (<anonymous>)\n    at IOSession.Session.onMessage (/home/bstaletic/Temp/ycmd/third_party/tsserver/lib/node_modules/typescript/lib/tsserver.js:131657:36)\n    at Interface.<anonymous> (/home/bstaletic/Temp/ycmd/third_party/tsserver/lib/node_modules/typescript/lib/tsserver.js:132950:27)\n    at Interface.emit (events.js:193:13)\n    at Interface._onLine (readline.js:307:10)\n    at Interface._normalWrite (readline.js:448:12)\n    at ReadStream.ondata (readline.js:164:10)\n    at ReadStream.emit (events.js:193:13)\n    at addChunk (_stream_readable.js:295:12)\n    at readableAddChunk (_stream_readable.js:276:11)\n    at ReadStream.Readable.push (_stream_readable.js:231:10)\n    at TTY.onStreamRead (internal/stream_base_commons.js:154:17)"}

The important part is that each response from TSServer needs to start with "Content-Length: <some number>"

Also, it looks like you didn't have let g:ycm_log_level='debug' in your vimrc, so the logs don't contain debug messages.

peterdutton · 2019-06-26T08:45:58Z

Thanks - I tried executing the command and it returns the "Content-Length: ..." at the beginning of the response.

Apologies, I mustn't have set the debug flag properly. I've done that now and updated the files in the gist.

obetame · 2019-09-19T02:01:29Z

I have same output error message too

Is you vim working properly? @peterdutton

peterdutton · 2019-09-21T07:54:38Z

No, I wasn't able to get it working unfortunately, so I'm looking at using a different completion plugin now.

bstaletic · 2019-09-21T08:21:58Z

Two things come to my mind:

Update the ycmd submodule to the latest master and see what happens.
Switch to the tern completer with ./install.py --tern-completer, if you are hitting this: Support AMD modules in Salsa microsoft/TypeScript#6942

puremourning · 2020-01-04T23:20:10Z

no follow-up, no new data. likely an environment issue. If there is any new information, please raise a new issue.

azizj1 · 2021-03-20T02:25:34Z

Still having this issue. Any workarounds?

puremourning · 2021-03-20T07:57:29Z
