Language Server crashing

[fleimgruber]

Julia version is 1.2. Installed Language Server and set lsp-julia-default-environment to that environment. On visiting a .jl buffer, I get the following in the *julia-ls::stderr* where my hunch is that the problem has to do with SymbolServer:

[ Info: Started symbol server
ERROR: EOFError: read end of file

stderr from client process:

ERROR: LoadError: MethodError: no method matching namemap(::Type{MathOptInterface.ActivationCondition})
The applicable method may be too new: running in world age 26094, while current world is 26109.
Closest candidates are:
  namemap(::Type{MathOptInterface.ActivationCondition}) at Enums.jl:189 (method too new to be called from this world context.)
  namemap(!Matched::Type{Base.MPFR.MPFRRoundingMode}) at Enums.jl:189

Process julia-ls stderr finished

[fleimgruber]

After some thought, should I report this upstream? Please let me know whether you think this does not have to do with lsp-julia itself.

[non-Jedi]

There appears to be an identical error filed at https://github.com/julia-vscode/julia-vscode/issues/850. Something specific to MathOptInterface perhaps. I'm going to go ahead and close this one in favor of the julia-vscode issue.

[fleimgruber]

The actual fix for this seems to be https://github.com/julia-vscode/SymbolServer.jl/pull/64. It would be nice if the next update of LanguageServer (shipped with lsp-julia) would include that change, i.e. probably the next release after 1.0.0.
