What version of Go are you using (go version)?

$ go version
go version devel go1.21-c0ac33c006 Thu Feb 23 15:24:16 2023 +0000 linux/amd64

Does this issue reproduce with the latest release?

No

What did you do?

$ go list -json="Export" -export=true crypto/internal/nistec

What did you expect to see?

{
	"Export": "/home/dominikh/.cache/go-build/87/87ca46f4197e1a35c09440c07ea6b3ff726c42cfaecd61820cc34c33544d59b7-d",
}

What did you see instead?

# crypto/internal/nistec
src/crypto/internal/nistec/p256_asm.go:322:3: invalid go:embed: build system did not supply embed configuration
{}

This is caused by c0ac33c which skips the computation of embed-related data when -json specifies a list of fields that doesn't include any embed-related fields. However, this fails to account for -export, which has to compile code, which needs a valid embed configuration.
