Empty string support in rcl_yaml_parser
How to pass empty string in yaml files so that rcl_yaml_parser can parse it successfully ?
Currently giving values like id : "" in the yaml leads to the error terminate called after throwing an instance of 'std::runtime_error'
what(): Unable to open file.
It would help if you can provide a little more context here -- and show an example bit of yaml that you're trying to load.
Thing is: you're asking a question about a cause that you've identified as being the cause of the exception, but it might be something else.
