"type is missing before a type separator"

[bobdobbs]

When following the installation instructions, I get to the step:

composer run-script --working-dir=vendor/felixfbecker/language-server parse-stub

The command runs for a while and then ends, notifying of an exception:

Parsing file:///home/mantis/opt/php-language-server/vendor/jetbrains/phpstorm-stubs/http/http.php

Script LanguageServer\ComposerScripts::parseStubs handling the parse-stubs event terminated with an exception

In TypeResolver.php line 203:
                                             
  A type is missing before a type separator

I don't have any experience with this package, but, I too, am experiencing this error upon initial install. I have supplied a stack trace, the relevant arguments, and the file being processed. For what it is worth, when the error is thrown, this is the first time an "&"(and) separator appears; all the prior separators were "|"(or). Hoping someone who's head is wrapped tightly around this codebase can identify the issue more quickly. Edit: I would note that the error is occurring on the parseTypes function in vendor/phpdocumentor/type-resolver/src/TypeResolver.php Yes, phpDocumentor is a dependency of this project, so there's a bug in phpDocumentor, or it's being fed bad data when parsing the stubs. At least, that is how it looks.
