OS: Ubuntu 20.04.3 LTS (Focal Fossa) Ruby: ruby 2.7.4p191 Solargraph: solargraph (0.44.1) Rubocop: rubocop (1.23.0)

When I open my project in VsCode, the warning starts:

Failed to start Solargraph: Error: [NoMethodError] private method `select' called for nil:NilClass

Here are my Rubocop and Solargraph .yml files:

The exclude setting in .solargraph.yml should either contain a list of values or be deleted altogether. An empty array is acceptable:

exclude: []

I'll look into a more graceful way of handling errors in config files.
