Crashes on my project in VsCode: Failure("Empty file") #525
Description
My code has a few dependencies so it will take some time to reproduce it. I'm trying on 4.12.1+flambda, ocamllsp 1.8.3
git clone git@github.com:Kakadu/OCanren.git -b bug-lsp-1 --depth=1 OCanren
cd OCanren
opam install z3 camlp5 ppx_expect benchmark --yes
dune build OCanren/src/OCanren.cmxa
code . OCanren/src/core/Core.mli -n
After opening the file in vscode, I get The OCaml Platform VS Code extension server crashed 5 times in the last 3 minutes. The server will not be restarted. and the following log in 'Output->OCaml Language Server': https://gist.github.com/Kakadu/d2584a02abeddb00d3450f00d2f4def9 Most interesting parts are:
[Error - 4:23:16 PM] Request textDocument/documentSymbol failed.
Message: uncaught exception
Code: -32603
[object Object]
and
ocamllsp: internal error, uncaught exception:
