# Monkey-patch to fix Solargraph 0.48.0 bug with Ruby 3.4+
# See: https://github.com/castwide/solargraph/issues/733
# Fixed in Solargraph PR #735 (merged Jan 7, 2025) but not in 0.48.0
# https://github.com/castwide/solargraph/pull/735/files
#
# Bug: node_range method crashes when passed nil node
# This happens, for example,
# with rescue clauses that don't assign exception to a variable
# Example: "rescue NameError" instead of "rescue NameError => e"
