TranspileYaml native implementation not found!

Error message

TranspileYaml native implementation not found!

What it means

Capability guard in transpileYaml (cubejs-backend-native): the loaded native module lacks a transpileYaml export, so YAML data model transpilation is unavailable. This is the fallback-build path where the native binary was substituted with a stub without that function.
