Reproduce the issue with the supplied OpenAPI declaration and the command using the cpp-tizen generator. Start by tracing the cpp-tizen generator's type mapping and generated include/template entry points for a string with format byte. Done means the generated project no longer references an unavailable ByteArray type or header and compiles with g++.
