raindrops: panic: interface conversion: astrav.Node is *astrav.CallExpr, not *astrav.FuncDecl

[bitfield]

This is a weird one!

Raindrops 8c8e0e3527c545289d89772cf235efe2 gives this result:

I know the "raindrops" exercise, so I'll try to make some specific suggestions about it, as well as the general code checks:
go test:         OK
go test -race:   SKIPPED
golint:          OK
gofmt:           OK
go vet:          OK
golangci-lint:   FAIL
raindrops.go:9:6: `main` is unused (deadcode)
func main() {
     ^

benchmarks:      SKIPPED
panic: interface conversion: astrav.Node is *astrav.CallExpr, not *astrav.FuncDecl

Here's the code:

package raindrops

import (
	"fmt"
	"strconv"
	"strings"
)

func main() {
	var number int
	fmt.Println("Enter number: ")
	fmt.Scan(&number)
	fmt.Println(number)

	fmt.Println("Result: ")
	fmt.Println(Convert(number))
}

//Convert number
func Convert(i int) string {
	bStr := []string{}

	if i%3 == 0 {
		bStr = append(bStr, "Pling")
	}

	if i%5 == 0 {
		bStr = append(bStr, "Plang")
	}
	if i%7 == 0 {
		bStr = append(bStr, "Plong")
	}

	if i%3 != 0 && i%5 != 0 && i%7 != 0 {
		bStr = append(bStr, strconv.Itoa(i))
	}

	return strings.Join(bStr, "")
}
