Solargraph fails to start in project using older version of bundler

I'm hoping to use Solargraph for some Rails projects at work. The installation goes well but the server fails to launch with Client 1 quit with exit code 1 and signal 0. I see the following messages in the LSP log

The project is using bundler 1.17.3. If I follow the suggestion and update bundler for the project to the latest version, the server is able to launch successfully. However, this isn't a long term solution for me since I'm not able to change the version of bundler we are using. Is this the expected behavior?

Hello! From your description, this sounds like a Solargraph-specific issue. I don't personally use it so I'm afraid I can't be of help. I'd suggest searching the https://github.com/castwide/solargraph repo if anyone else has ran into the same issue. You could perhaps also try installing an older version of Solargraph, like :LspInstall [email protected]
