Unable to attach to process using netcoredbg

[rudiejd]

Debug adapter definition and debug configuration

dap.adapters.netcoredbg = {
  type = 'executable',
  command = 'netcoredbg',
  args = { '--interpreter=vscode' },
}

dap.configurations.cs = {
  {
    type = 'netcoredbg',
    name = 'Attach - netcoredbg',
    request = 'attach',
    processId = require('dap.utils').pick_process
  },
}

Debug adapter version

3.0.0-1012

Steps to Reproduce

1. Use the attach configuration
2. Pick any process
3. Observe the error

Expected Result

Should attach to process and begin debugging

Actual Result

Error on attach: can't parse: [json.exception.out_of_range.403] key 'processId' not found

This looks similar to https://github.com/mfussenegger/nvim-dap/issues/356

If I can figure out a configuration for C# that avoids this issue, I'll contribute it to the server configurations list
