Runtime error by using of function db.Insert

[giesan]

Hello everyone,

I am currently using version v2.0.0-alpha.3 and get the following error message when using the db.Insert function

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x7c3e2e]

goroutine 1 [running]:

exit status 2

Here is my code I tried with.

package main

import (
	c "github.com/ostafen/clover/v2"
	d "github.com/ostafen/clover/v2/document"
)

func main() {

	db, _ := c.Open(".")
	defer db.Close()

	db.CreateCollection("todos")

	// Create todos
	todo1 := d.NewDocument()
	todo1.Set("title", "delectus aut autem")
	todo1.Set("completed", false)
	todo1.Set("userId", 1)

	todo2 := d.NewDocument()
	todo2.Set("title", "quis ut nam facilis et officia qui")
	todo2.Set("completed", false)
	todo2.Set("userId", 2)

	var docs = make([]*d.Document, 2)
	docs = append(docs, todo1)
	docs = append(docs, todo2)

	db.Insert("todos", docs...)
}

Am I doing something wrong?
Best regards

This snippet results in a slice with 4 documents, with the first 2 being nil. Try replacing:

var docs = make([]*d.Document, 2)

with:

var docs = make([]*d.Document, 0, 2)
