Reports invalid method overloads (...). A method overload is only valid if there is exactly one other non-overloaded definition for the method.

A quick fix is available to remove the invalid method overload.

Example:

class Example
  # Cannot find a non-overloaded declaration for method 'call' of class 'Example'
  def call: -> untyped | ...
end

After the quick fix:

class Example
  def call: -> untyped
end
