Are you working in a nodejs project (i.e.: with package.json, tsconfig.json, built by tsc?)
If so, I'm having a similar issue. Deno LSP seems to detect all of that configuration correctly, however, I get no inlay hints. And "go to definition" doesn't go to the
.ts
.ts
file (where the JSDoc is) but instead goes to the file type definition (without JSDoc comments).
As a result, I'm going to have to remove deno as my default TS LSP config and fall back to the helix default which gets this correct. (at least for my work machine, since my team uses Node.)
