custom version: %w

Error message

custom version: %w

What it means

Wrapping error in Builder.goBuild: createVersion failed to derive the version string for the custom binary (e.g. ldflags version assembly from the configured version failed). The build aborts before spawning 'go build'; the wrapped error names the exact parsing/generation failure.
