Python Language Server conflicting with GraphQL extension

Environment data

• VS Code version: 1.51
• Extension version (available under the Extensions sidebar): v2020.11.371526539
• OS and version: macOS 10.15 Catalina
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda Python 3.8
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
• Relevant/affected Python packages and their versions: N/A
• Relevant/affected Python-related VS Code extensions and their versions: graphql-0.13.12
• Value of the python.languageServer setting: true

Expected behaviour

Execute GraphQL queries to a remote endpoint successfully, inside of a multi-root, multi-language workspace.

Actual behaviour

Installing and running this extension inside of my Python Workspace with the listed configuration generates the following error

  ERR name must not be falsy: Error: name must not be falsy

The errors do not appears to be from the Language Server, but googling for the error itself yields only issues related to the Python Language Server. I am able to run the graphql extensions inside a single language, non multi-root workspace (From my screenshot above). Search Reference

Steps to reproduce:

• Create a multi-root workspace
• Initialize the Python Language Server
• Install graphql from the Extensions marketplace
• Configure GraphQL with a remote or local schema
• Create a query file
• Run ‘Execute Query’
• The query window will return an empty screen instead of data.

@luabud Not a problem. I’ll try out Pylance and see if it resolves the issue.

Is there an EOL for the Python Language Server in favor of Pylance?

[luabud]

We have recently released a new and more performant language server called Pylance which could solve this issue you are reporting. You can download Pylance from the marketplace and install it alongside the core Python extension. Because our team’s development efforts have shifted to support the new language server, we’d encourage you to try it out.
