Omni completion doesn't work: complete/completion mismatch

[ilaitinen]

vim-rescript tries to use complete:

The underlying rescript-editor-analysis.exe expects completion:

Yeah that was a legit change from this commit which I didn't notice until now: https://github.com/rescript-lang/rescript-vscode/commit/d8183100dc58bb9c5efd3711c1fb3eae301ffa80

Since we are vendoring the language server right now, we may even change this right after updating to the latest LSP.
