Ask HN: Why am I always stuck working on legacy software

I never seem to get picked for the new projects that involve new tech stacks and migration efforts. At my current company I am still maintaining an old codebase and Oracle database where some peers are working on migration to AWS and snowflake. Even at previous jobs I was always staffed on the unimportant legacy projects despite expressing interest in newer exciting projects . I do try to self learn and get certifications but somehow never get chosen to work on new exciting projects . Am I a bad engineer or do I come across wrong to management ? My performance reviews go great. What can I do or change ?
