Inlay hints not working in typescript?

[SKyletoft]

I'm using typescript with the ts-ls server in Emacs from master on NixOS.

I have

(setq lsp-javascript-display-parameter-name-hints 'all
        lsp-javascript-display-parameter-name-hints-when-argument-matches-name nil
        lsp-javascript-display-variable-type-hints t
        lsp-javascript-display-return-type-hints t
        lsp-javascript-display-property-declaration-type-hints t)
(setq-local lsp-ui-sideline-show-symbol nil)
(lsp)

in my typescript-ts-mode hook. None of it is being respected. What am I missing? Inlay hints are enabled and work in other languages.
The manual (lsp) call is to make sure direnv is called first (nix things). I'm still getting warnings and errors and types in popups.
