Presumed failure when running with php-language-server

[joaotavora]

Hi @felixfbecker, opening this issue here as you mentioned in joaotavora/eglot#1 (comment)

When I pass this JSONRPC to the php-language-server:

Content-Length: 888

{"jsonrpc":"2.0","id":205,"method":"initialize","params":{"processId":10335,"rootUri":"file:///home/capitaomorte/Source/PhP/hello-world/","capabilities":{"workspace":{"applyEdit":true,"workspaceEdit":{"documentChanges":false},"didChangeWatchesFiles":{"dynamicRegistration":true},"symbol":{"dynamicRegistration":false}},"textDocument":{"synchronization":{"dynamicRegistration":false,"willSave":true,"willSaveWaitUntil":true,"didSave":true},"completion":{"dynamicRegistration":false},"hover":{"dynamicRegistration":false},"signatureHelp":{"dynamicRegistration":false},"references":{"dynamicRegistration":false},"definition":{"dynamicRegistration":false},"documentSymbol":{"dynamicRegistration":false},"documentHighlight":{"dynamicRegistration":false},"rename":{"dynamicRegistration":false},"publishDiagnostics":{"relatedInformation":false}},"experimental":null},"initializationOptions":[]}}

(The first two lines are CRLF). It replies back with this stacktrace

-32603: TypeError: Argument 2 passed to LanguageServer\LanguageServer::initialize() must be of the type string or null, integer given, called in /home/capitaomorte/Source/PhP/hello-world/vendor/felixfbecker/advanced-json-rpc/lib/Dispatcher.php on line 164 and defined in /home/capitaomorte/Source/PhP/hello-world/vendor/felixfbecker/language-server/src/LanguageServer.php:168

Curiously, if I pass null for the processId, it works!
