Based on the error logs in https://github.com/mfussenegger/nvim-dap/issues/254, it appears the problem is the variables request with the empty body, represented as an empty array instead of an empty hash. I might be able to convert the value to avoid this particular error, but even given that change, I think the request is invalid according to the DAP specification.

Agree that it is invalid according to the DAP specification. As far as I could tell the request isn't coming from nvim-dap itself, but must be coming from one of the extensions for it.

FWIW, I'm also getting this, but using:

• both ruby 2.7.4 and 3.0.2
• readapt 1.4.3
• OSX
• neovim 0.5.1 (homebrew)
• nvim-dap rev b01b0be9a710cc7879e7cc53a40996be83fb88e4

I'm closing this as it was likely an issue with the neovim plugin. If problems persist, please feel free to open a new issue.
