find go.work: %w

Error message

find go.work: %w

What it means

Wrap from syncModReplaceAndTidy when `go env GOWORK` fails in the module directory, i.e. the go toolchain could not be invoked to detect an active go.work file. Without this, replace-directive overrides cannot be synced safely.

Solutions

1. Verify a Go toolchain is installed and on PATH in the generation environment
2. Run `go env GOWORK` manually in the module dir to see the failure
3. Check GOFLAGS/GOCACHE settings that might break go env execution
