Some services methods (getCompletionEntryDetails and getCompletionEntrySymbols) have additional parameters. Plugins that wrap the language service must pass these parameters along to the original implementation. See #19507

[bryanforbes]

This is due to tsserver outputting some warnings from npm on stdout (for instance, npm WARN 2.6 No description) when it runs the automatic type acquisition. Invalid output from tsserver should be skipped.

[puremourning]

I feel like invalid output from npm is the tsserver stdout is a straight up tsserver bug?

[bryanforbes]

I agree (and so do they), but they released 2.6.1 (as the major TS2.6 release) with this behavior and it's out in the wild. Until they release a new version, ycmd won't work.

[TommyX12]

Right now the referenced ycmd repo hasn't been updated yet, so even though this is solved in ycmd, it still isn't working in YCM.

[bstaletic]

@TommyX12 If you're in a hurry to get this solved in YCM, at least for yourself, you can go into your ycmd directory and pull the fixed ycmd revision.

You fellows are absolute lifesavers! I love you guys <3
