    Your Regular Expression /#{expression_regexp.source}/
    matches multiple parameter types with regexp /#{parameter_type_regexp}/:
       #{parameter_type_names(parameter_types)}
    I couldn't decide which one to use. You have two options:
    1) Use a Cucumber Expression instead of a Regular Expression. Try one of these:
       #{expressions(generated_expressions)}
    2) Make one of the parameter types preferential and continue to use a Regular Expression.
